Catalpa speciosa

Common Name: catalpa

Type: Tree

Family: Bignoniaceae

Native Range: United States and Canada

Zone: 4 to 8

Height: 40.00 to 70.00 feet

Spread: 20.00 to 50.00 feet

Bloom Time: May to June

Bloom Description: White with purple and yellow interior spotting

Sun: Full sun to part shade

Culture

Easily grown in average, medium to wet, well-drained soils in full sun to part shade. Tolerant of a wide range of soil conditions including both wet and dry soils. Tolerant of seasonal flooding. Prefers moist fertile loams.

Noteworthy Characteristics

Northern catalpa is a medium to large, deciduous tree that typically grows to 40-70’ (less frequently to 100’) tall with an irregular, open-rounded to narrow-oval crown. It is native to a relatively small area extending from western Tennessee, northeastern Arkansas and the lowlands of southeastern Missouri north to southern Illinois and southern Indiana. In Missouri, it typically occurs along streams, bluff bases and in both low and upland woods (Steyermark). Broad ovate to ovate-oblong leaves (to 12” long) are pointed at the tips and rounded to cordate at the bases. Leaves are light green to yellow green above and densely pubescent below. Foliage turns an undistinguished yellow in fall. Flowers can be a real showstopper, however. Bell-shaped, orchid-like white flowers (to 2” long) with purple and yellow inner spotting appear in panicles in late spring (late May to early June in St. Louis). Flowers give way to long slender green seedpods (12-22” long). The seedpods mature in fall to dark brown and then split open lengthwise to release the seeds within. Seedpods give rise to the common name of cigar tree, although they actually are longer and thinner than most cigars. Abundant pods are produced every 2 to 3 years. Bark of mature trees is fissured, prominently ridged and pale gray-brown. The leaves of this species do not emit an unpleasant aroma when bruised as is the case with the similar southern catalpa (Catalpa bignonioides).

Problems

No serious insect or disease problems. Susceptible to verticillium wilt, leaf spots, mildew and twig blight. The larvae (caterpillars) of the catalpa sphinx moth may do considerable damage when feeding on the leaves.

This tree is in my neighbour´s garden. I took this from a second floor balcony so you have some idea of the height of this tree – four stories.

Garden Uses

A mature, symmetrically rounded catalpa tree can be a tree of great beauty, particularly in spring when the foliage is young and the flowers are in bloom. Unfortunately, it is otherwise a rather coarse tree that many believe does not deserve a prominent place in the landscape. Branches are brittle and mature trees infrequently exhibit classic form. Foliage also tends to depreciate as the growing season progresses, the large leaves being subject to damage from hail, wind, insects and sometime disease. It has been widely planted in urban areas as a street tree and lawn tree, and can also be effectively used in the landscape for difficult areas such as moist low spots or dry areas with poor soils.

Datura stramonium – Jimson Weed

Datura stramonium, known by the common names Jimson weed, Devil’s snare or datura, is a plant in the Solanaceae (nightshade) family. It is believed to have originated in the Americas, but is now found around the world. Other common names for D. stramonium include thornapple and moon flower, and it has the Spanish name Toloache.

For centuries, datura has been used as a herbal medicine to relieve asthma symptoms and as an analgesic during surgery or bonesetting. It is also a powerful hallucinogen and deliriant, which is used spiritually for the intense visions it produces. However, the tropane alkaloids which are responsible for both the medicinal and hallucinogenic properties are fatally toxic in only slightly higher amounts than the medicinal dosage, and careless use often results in hospitalizations and deaths.

Scientific classification
Kingdom: Plantae
(unranked): Angiosperms
(unranked): Eudicots
(unranked): Asterids
Order: Solanales
Family: Solanaceae
Genus: Datura
Species: D. stramonium

Description

D. stramonium is a foul-smelling, erect annual, freely branching herb that forms a bush up to 2 to 5 feet (60–150 cm) tall.^[4][5][6]

The root is long, thick, fibrous and white. The stem is stout, erect, leafy, smooth, and pale yellow-green. The stem forks off repeatedly into branches, and at each fork forms a leaf and a single, erect flower.^[6]

The leaves are approximately 3 to 8 inches (8–20 cm) long, smooth, toothed,^[5] soft, irregularly undulate.^[6] The upper surface of the leaves is a darker green, and the bottom is a light green.^[5] The leaves have a bitter and nauseating taste, which is imparted to extracts of the herb, and remains even after the leaves have been dried.^[7]

Datura stramonium generally flowers throughout the summer. The fragrant flowers are trumpet-shaped, white to creamy or violet, and 2 ¹⁄₂ to 3 ¹⁄₂ inches (6–9 cm) long, and grow on short stems from either the axils of the leaves or the places where the branches fork. The calyx is long and tubular, swollen at the bottom, and sharply angled, surmounted by five sharp teeth. The corolla, which is folded and only partially open, is white, funnel-shaped, and has prominent ribs. The flowers open at night, emitting a pleasant fragrance and is fed upon by nocturnal moths.^[6]

The egg-shaped seed capsule is 1 to 3 inches (3–8 cm) in diameter and either covered with spines or bald. At maturity it splits into four chambers, each with dozens of small black seeds.^[6]

Range and habitat

Datura stramonium is native to North America, but was spread to the Old World early. It was scientifically described and named by Swedish botanist Carl Linnaeus in 1753, although it had been described a century earlier by herbalists, such as Nicholas Culpeper. Today, it grows wild in all the world’s warm and moderate regions, where it is found along roadsides and at dung-rich livestock enclosures. In Europe, it is found as a weed on wastelands and in garbage dumps.

The seed is thought to be carried by birds and spread in their droppings. Its seeds can lie dormant underground for years and germinate when the soil is disturbed. People who discover it growing in their gardens, and are worried about its toxicity, have been advised to dig it up or have it otherwise removed.

Toxicity

Main article: Datura: Toxicity

All parts of Datura plants contain dangerous levels of the tropane alkaloids atropine, hyoscyamine and scopolamine which are classified as deliriants, or anticholinergics. There is a high risk of fatal overdose amongst uninformed users, and many hospitalizations occur amongst recreational users who ingest the plant for its psychoactive effects.

The amount of toxins varies widely from plant to plant. There can be as much as a 5:1 variation between plants, and a given plant’s toxicity depends on its age, where it is growing, and the local weather conditions. Additionally, within a given datura plant, toxin concentration varies by part and even from leaf to leaf. When the plant is younger, the ratio of scopolamine to atropine is approximately 3:1; after flowering, this ratio is reversed, with the amount of scopolamine continuing to decrease as the plant gets older. This variation makes Datura exceptionally hazardous as a drug. In traditional cultures, a great deal of experience with and detailed knowledge of Datura was critical in order to minimize harm. An individual datura seed contains about 0.1 mg of atropine, and the approximate fatal dose for adult humans is >10 mg atropine or >2–4 mg scopolamine.

Datura intoxication typically produces delirium (as contrasted to hallucination); hyperthermia; tachycardia; bizarre behavior; and severe mydriasis with resultant painful photophobia that can last several days. Pronounced amnesia is another commonly reported effect.The onset of symptoms generally occurs approximately 30 minutes to an hour after smoking the herb. These symptoms generally last from 24 to 48 hours, but have been reported in some cases to last as long as 2 weeks.

As with other cases of anticholinergic poisoning, intravenous physostigmine can be administered in severe cases as an antidote.

Medicinal uses

Datura has long been used as an extremely effective treatment for asthma symptoms. The active anti-asthmatic agent is atropine, which causes paralysis of the pulmonary branches of the lungs, eliminating the spasms that cause the asthma attacks. The leaves are generally smoked either in a cigarette or a pipe. This practice of smoking datura to relieve asthma has its origins in traditional Ayurvedic medicine in India. After this was discovered during the late 18th century by James Anderson, the English Physician-General of the East India Company, the practice quickly became popular in Europe.

The Zuni used to use datura as an analgesic, to render patients unconscious while broken bones were set. The Chinese also used it in this manner, as a form of anaesthesia during surgery.

Atropine and scopolamine (both of which are found in very high concentrations in datura) are muscarinic antagonists which can be used to treat Parkinson’s disease and motion sickness, and to inhibit parasympathetic stimulation of the urinary tract, respiratory tract, GI tract, heart and eye.

Datura can be used to assist in the process of breaking drug addictions, by reducing the symptoms of delirium tremens and morphine withdrawals.

Other medicinal uses for datura include providing relief from sore throat or toothache and getting rid of parasites.

Datura should be avoided by patients with heart problems, glaucoma, enlarged prostate, urinary difficulties, fluid buildup in the lungs, or bowel obstructions.

Spiritual uses

The ancient inhabitants of what is today central and southern California used to ingest the small black seeds of datura to “commune with deities through visions”. Across the Americas, other indigenous peoples such as the Algonquin, Cherokee, Marie Galente and Luiseño also utilized this plant in sacred ceremonies for its hallucinogenic properties. In Ethiopia, some students and debtrawoch (lay priests), use D. stramonium to “open the mind” to be more receptive to learning, and creative and imaginative thinking.

The common name “datura” has its roots in ancient India, where the plant is considered particularly sacred—believed to be a favorite of the Hindu god Shiva Nataraja.

Cultivation

Datura prefers rich, calcareous soil. Adding nitrogen fertilizer to the soil will increase the concentration of alkaloids present in the plant. Datura can be grown from seed, which is sown with several feet between each plant. Datura is sensitive to frost, and so should be sheltered during cold weather. The plant is harvested when the fruits are ripe, but still green. To harvest, the entire plant is cut down, the leaves are stripped from the plant, and everything is left to dry. When the fruits begin to burst open, the seeds are harvested. A single intensively planted acre can produce 1,000 to 1,500 pounds (1,100–1,700 kg/ha) of leaf and 700 pounds (780 kg/ha) of seed.^[29]

Etymology

The genus name is derived from dhatura, an ancient Hindu word for a plant. Stramonium is originally from Greek, strychnos στρύχνος “nightshade” and maniakos μανιακός “mad”.

In the United States the plant is called jimson weed, or more rarely Jamestown weed; it got this name from the town of Jamestown, Virginia, where British soldiers consumed it while attempting to suppress Bacon’s Rebellion. They spent eleven days in altered mental states:

The James-Town Weed (which resembles the Thorny Apple of Peru, and I take to be the plant so call’d) is supposed to be one of the greatest coolers in the world. This being an early plant, was gather’d very young for a boil’d salad, by some of the soldiers sent thither to quell the rebellion of Bacon (1676); and some of them ate plentifully of it, the effect of which was a very pleasant comedy, for they turned natural fools upon it for several days: one would blow up a feather in the air; another would dart straws at it with much fury; and another, stark naked, was sitting up in a corner like a monkey, grinning and making mows [grimaces] at them; a fourth would fondly kiss and paw his companions, and sneer in their faces with a countenance more antic than any in a Dutch droll.

In this frantic condition they were confined, lest they should, in their folly, destroy themselves — though it was observed that all their actions were full of innocence and good nature. Indeed, they were not very cleanly; for they would have wallowed in their own excrements, if they had not been prevented. A thousand such simple tricks they played, and after eleven days returned themselves again, not remembering anything that had passed.

Lily – Lilium

 

 Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have “lily” in their common name but are not related to true lilie

 

Scientific classification
Kingdom: Plantae
(unranked): Angiosperms
(unranked): Monocots
Order: Liliales
Family: Liliaceae
Subfamily: Lilioideae
Genus: Lilium

Names

The botanic name Lilium is the Latin form and is a Linnaean name. The Latin name is derived from the Greek λείριον, leírion, generally assumed to refer to true, white lilies as exemplified by the Madonna lily.^[1] The word was borrowed from Coptic (dial. Fayyumic) hleri, from standard hreri, from Demotic hrry, from Egyptian hrṛt “flower”. Meillet maintains that both the Egyptian and the Greek word are possible loans from an extinct, substratum language of the Eastern Mediterranean. The Greeks also used the word κρῖνον, krīnon, albeit for non-white lilies.The term “lily” has in the past been applied to numerous flowering plants, often with only superficial resemblance to the true lily, including lotus, ranunculus, tulip, iris, anemone, agapanthus, zantedeschia, daylily, and others. All English translations of the Bible render the Hebrew shūshan, shōshan, shōshannā as “lily”, but the “lily among the thorns” of Song of Solomon, for instance, may be the honeysuckle.

Range

The range of lilies in the Old World extends across much of Europe, across most of Asia to Japan, south to India, and east to Indochina and the Philippines. In the New World they extend from southern Canada through much of the United States. They are commonly adapted to either woodland habitats, often montane, or sometimes to grassland habitats. A few can survive in marshland and epiphytes are known in tropical southeast Asia. In general they prefer moderately acidic or lime-free soils.Lilies are tall perennials ranging in height from 2–6 ft (60–180 cm). They form naked or tunicless scaly underground bulbs which are their overwintering organs. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are deeply buried, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at some depth in the soil, and each year the new stem puts out adventitious roots above the bulb as it emerges from the soil. These roots are in addition to the basal roots that develop at the base of the bulb.The flowers are large, often fragrant, and come in a range of colours including whites, yellows, oranges, pinks, reds and purples. Markings include spots and brush strokes. The plants are late spring- or summer-flowering. Flowers are borne in racemes or umbels at the tip of the stem, with six tepals spreading or reflexed, to give flowers varying from funnel shape to a “Turk’s cap”. The tepals are free from each other, and bear a nectary at the base of each flower. The ovary is ‘superior’, borne above the point of attachment of the anthers. The fruit is a three-celled capsule.Seeds ripen in late summer. They exhibit varying and sometimes complex germination patterns, many adapted to cool temperate climates.Naturally most cool temperate species are deciduous and dormant in winter in their native environment. But a few species which distribute in hot summer and mild winter area (Lilium candidum, Lilium catesbaei,Lilium longiflorum) lose leaves and remain relatively short dormant in Summer or Autumn, sprout from Autumn to winter, forming dwarf stem bearing a basal rosette of leaves until accept enough chilling requirement, the stem begins to elongate while warming.

Ecology

Lilies are used as food plants by the larvae of some Lepidoptera species including the Dun-bar.

Toxicity

Some Lilium species are toxic to cats. This is known to be so especially for L. longiflorum though other Lilium and the unrelated Hemerocallis can also cause the same symptoms. The true mechanism of toxicity is undetermined, but it involves damage to the renal tubular epithelium (composing the substance of the kidney and secreting, collecting, and conducting urine), which can cause acute renal failure. Veterinary help should be sought, as a matter of urgency, for any cat that is suspected of eating any part of a lily – including licking pollen that may have brushed onto its coat.

Cultivation

Many species are widely grown in the garden in temperate and sub-tropical regions. They may also be grown as potted plants. Numerous ornamental hybrids have been developed. They can be used in herbaceous borders, woodland and shrub plantings, and as patio plants. Some lilies, especially Lilium longiflorum, form important cut flower crops. These may be forced for particular markets; for instance, L. longiflorum for the Easter trade, when it may be called the Easter lily.Lilies are usually planted as bulbs in the dormant season. They are best planted in a south-facing, slightly sloping aspect, in sun or part shade, at a depth 2½ times the height of the bulb (except L. candidum which should be planted at the surface). Most prefer a porous, loamy soil, and good drainage is essential. Most species bloom in July or August. The flowering periods of certain lily species begin in late spring, while others bloom in late summer or early autumn.^[8] They have contractile roots which pull the plant down to the correct depth, therefore it is better to plant them too shallowly than too deep. A soil pH of around 6.5 is generally safe. The soil should be well-drained, and plants must be kept watered during the growing season. Some plants have strong wiry stems, but those with heavy flower heads may need staking.

Stargazer

Numerous forms, mostly hybrids, are grown for the garden. They vary according to the species and interspecific hybrids that they derived from, and are classified in the following broad groups:

• Asiatic hybrids (Division I). These are plants with medium sized, upright or outward facing flowers, mostly unscented. They are derived from central and East Asian species and interspecific hybrids, including L. amabile, L. bulbiferum, L. callosum, L. cernuum, L. concolor, L. dauricum, L. davidii, L. × hollandicum, L. lancifolium (syn. L. tigrinum), L. lankongense, L. leichtlinii, L. × maculatum, L. pumilum, L. × scottiae, L. wardii and L. wilsonii.
• Martagon hybrids (Division II). These are based on L. × dalhansonii, L. hansonii, L. martagon, L. medeoloides and L. tsingtauense. The flowers are nodding, Turk’s cap style (with the petals strongly recurved).
• Candidum (Euro-Caucasian) hybrids (Division III). This includes mostly European species: L. candidum, L. chalcedonicum, L. kesselringianum, L. monadelphum, L. pomponium, L. pyrenaicum and L. × testaceum.
• American hybrids (Division IV). These are mostly taller growing forms, originally derived from L. bolanderi, L. × burbankii, L. canadense, L. columbianum, L. grayi, L. humboldtii, L. kelleyanum, L. kelloggii, L. maritimum, L. michauxii, L. michiganense, L. occidentale, L. × pardaboldtii, L. pardalinum, L. parryi, L. parvum, L. philadelphicum, L. pitkinense, L. superbum, L. ollmeri, L. washingtonianum and L. wigginsii. Many are clump-forming perennials with rhizomatous rootstocks.
• Longiflorum hybrids (Division V). These are cultivated forms of this species and its subspecies. They are most important as plants for cut flowers, and are less often grown in the garden than other hybrids.
• Trumpet lilies (Division VI), including Aurelian hybrids (with L. henryi). This group includes hybrids of many Asiatic species and their interspecific hybrids, including L. × aurelianense, L. brownii, L. × centigale, L. henryi, L. × imperiale, L. × kewense, L. leucanthum, L. regale, L. rosthornii, L. sargentiae, L. sulphureum and L. × sulphurgale. The flowers are trumpet shaped, facing outward or somewhat downward, and tend to be strongly fragrant, often especially night-fragrant.
• Oriental hybrids (Division VII). These are based on hybrids L. auratum and L. speciosum, together with crossbreeds from several species native to Japan, including L. nobilissimum, L. rubellum, L. alexandrae, and L. japonicum. They are fragrant, and the flowers tend to be outward facing. Plants tend to be tall, and the flowers may be quite large. The whole group are sometimes referred to as “stargazers” because they appear to look upwards. (For the specific cultivar, see Lilium ‘Stargazer’.)
• Other hybrids (Division VIII). Includes all other garden hybrids.
• Species (Division IX). All natural species and naturally occurring forms are included in this group.

And there are subdivisions classified by flower aspect and form. EX:(flower aspect/flower form)Flower aspect:

• a up-facing
• b out-facing
• c down-facing

Flower form:

• a trumpet-shaped
• b bowl-shaped
• c flat (or with tepal tips recurved)
• d tepals strongly recurved (with the Turk’s cap form as the ultimate state)

Many newer commercial varieties are developed by using new technologies such as in vitro pollination, ovary culture and embryo rescue.

Pests and diseases

Aphids may infest plants. Leatherjackets feed on the roots. Larvae of the Scarlet lily beetle can cause serious damage to the stems and leaves. The scarlet beetle lays its eggs and completes its life cycle only on true lilies. Oriental, rubrum, tiger and trumpet lilies as well as Oriental trumpets (orienpets) and Turk’s cap lilies and native North American lily species are all vulnerable, but the beetle prefers some types. The beetle could also be having an effect on native Canada species and some rare and endangered species found in northeastern North America. Day lilies are excluded from this category. Plants can suffer from damage caused by mice, deer and squirrels. Slugs, snails and millipedes attack seedlings, leaves and flowers. Brown spots on damp leaves may signal botrytis (also known as lily disease). Various fungal and viral diseases can cause mottling of leaves and stunting of growth.

Propagation and growth

Lilies can be propagated in several ways;

• by division of the bulbs
• by growing-on bulbils which are adventitious bulbs formed on the stem
• by scaling, for which whole scales are detached from the bulb and planted to form a new bulb
• by seed; there are many seed germination patterns, which can be complex
• by micropropagation techniques (which include tissue culture);commercial quantities of lilies are often propagated in vitro and then planted out to grow into plants large enough to sell.

According to a study done by Anna Pobudkiewicz and Jadwiga the use of flurprimidol foliar spray helps aid in the limitation of stem elongation in oriental lilies.

Culinary and herb uses

China

Lilium bulbs are starchy and edible as root vegetables, although bulbs of some species may be very bitter. The non-bitter bulbs of L. lancifolium, L. pumilum, and especially L. brownii (Chinese: 百合 干; pinyin: bǎihé gān) and Lilium davidii var unicolor are grown on a large scale in China as a luxury or health food, and are most often sold in dry form for herb, the fresh form often appears with other vegetables. The dried bulbs are commonly used in the south to flavor soup. Lily flowers are also said to be efficacious in pulmonary affections, and to have tonic properties. Lily flowers and bulbs are eaten especially in the summer, for their perceived ability to reduce internal heat. They may be reconstituted and stir-fried, grated and used to thicken soup, or processed to extract starch. Their texture and taste draw comparisons with the potato, although the individual bulb scales are much smaller. There are also species which are meant to be suitable for culinary and/or herb uses. There are five traditional lily species whose bulbs are certified and classified as “vegetable and non-staple foodstuffs” on the National geographical indication product list of China.

Culinary use:

And there are researches about the selection of new varieties of edible lilies from the horticultural cultivars, such as ‘Batistero’ and ‘California’ among 15 lilies in Beijing, and ‘Prato’ and ‘Small foreigners’ among 13 lilies in Ningbo.

Japan

Yuri-ne (lily-root) is also common in Japanese cuisine, especially as an ingredient of chawan-mushi (savoury egg custard). The major lilium species cultivated as vegetable are L. leichtlinii var. maximowiczii, L. lancifolium, and L. auratum

Taiwan

The parts of lilium species which are officially listed as food material are the flower and bulbs of Lilium lancifolium Thunb., Lilium brownii F. E. Brown var. viridulum Baker, Lilium pumilum DC., Lilium candidum Loureiro. Most edible lily bulbs which can be purchased in a market are mostly imported from mainland China (only in the scale form, and most marked as 蘭州百合 Lilium davidii var unicolor) and Japan (whole bulbs, should mostly be L. leichtlinii var. maximowiczii). There are already commercially available organic growing and normal growing edible lily bulbs. The varieties are selected by the Taiwanese Department of Agriculture from the Asiatic lily cultivars that are imported from the Netherlands; the seedling bulbs must be imported from the Netherlands every year.

South Korea

The lilium species which are officially listed as herbs are 이 약은 참나리 Lilium lancifolium Thunberg; 백합 Lilium brownii var. viridulun Baker; 또는 큰솔나리 Lilium pumilum DC.

The “lily” flower buds known as jīnzhēn (金针, “golden needles”) in Chinese cuisine are actually from the daylily Hemerocallis fulva.

Taxonomy

Taxonomical division in sections follows the classical division of Comber, species acceptance follows the World Checklist of Selected Plant Families, the taxonomy of section Pseudolirium is from the Flora of North America, the taxonomy of Section Liriotypus is given in consideration of Resetnik et al. 2007, the taxonomy of Chinese species (various sections) follows the Flora of China  and the taxonomy of Section Archelirion follows Nishikawa et al. as does the taxonomy of Section Archelirion.

There are seven sections;

• Martagon
• Pseudolirium
• Liriotypus
• Archelirion
• Sinomartagon
• Leucolirion
• Daurolirion

Some species formerly included within this genus have now been placed in other genera. These genera include Cardiocrinum, Notholirion, Nomocharis and Fritillaria.

Poppy

A Poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae. Poppies are herbaceous plants, often grown for their colourful flowers. One species of poppy, Papaver somniferum produces edible seeds, and is also the source of the crude drug opium which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as analgesic and narcotic medicinal and recreational drugs. Following the trench warfare which took place in the poppy fields of Flanders, during the 1st World War, red poppies have become a symbol of remembrance of soldiers who have died during wartime.

Description

Poppies are herbaceous annual, biennial or short-lived perennial plants. Some species are monocarpic, dying after flowering. Poppies can be over 4 feet tall with flowers up to six inches across. The flowers have 4 to 6 petals, many stamens forming a conspicuous whorl in the centre of the flower and an ovary consisting of from 2 to many fused carpels. The petals are showy, may be of almost any color and some have markings. The petals are crumpled in the bud and as blooming finishes, the petals often lie flat before falling away. Poppies are in full bloom late spring to early summer.^[1] Most species secrete latex when injured. Bees use poppies as a pollen source. The pollen of the oriental poppy, Papaver orientale, is dark blue, that of the field or corn poppy (Papaver rhoeas) is dark green to grey.^[2] The opium poppy, Papaver somniferum, is mainly grown in eastern and southern Asia, and South Eastern Europe. It is believed that it originated in the Mediterranean region ^[3]

Poppies belong to the subfamily Papaveroideae of the family Papaveraceae, which includes the following genera:

• Papaver – Papaver rhoeas, Papaver somniferum, Papaver orientale, Papaver nudicaule
• Eschscholzia – Eschscholzia californica
• Meconopsis – Meconopsis cambrica, Meconopsis napaulensis
• Stylophorum – celandine poppy
• Argemone – prickly poppy
• Romneya – matilija poppy and relatives
• Canbya – pygmy poppy
• Stylomecon – wind poppy
• Arctomecon – desert bearpaw poppy
• Hunnemannia – tulip poppy
• Dendromecon – tree poppy

 

Uses

The flowers of most poppy species are attractive and are widely cultivated as annual or perennial ornamental plants. This has resulted in a number of commercially important cultivars, such as the Shirley poppy, a cultivar of Papaver rhoeas and semi-double or double (flore plena) forms of the opium poppy Papaver somniferum and oriental poppy (Papaver orientale). Poppies of several other genera are also cultivated in gardens. A few species have other uses, principally as sources of drugs and foods. The opium poppy is widely cultivated and its worldwide production is monitored by international agencies. It is used for production of dried latex and opium, the principal precursor of narcotic and analgesic opiates such as morphine, heroin and codeine. Poppy seeds are rich in oil, carbohydrates, calcium, and protein. Poppy oil is often used as cooking oil, salad dressing oil, or in products such as margarine. Poppy oil can also be added to spices for cakes, or breads. Poppy products are also used in different paints, varnishes, and some cosmetics (Jonsson and Krzymanski, 1989).

Symbolism

Poppies have long been used as a symbol of sleep, peace, and death: Sleep because of the opium extracted from them, and death because of the common blood-red color of the red poppy in particular. In Greek and Roman myths, poppies were used as offerings to the dead.^[4] Poppies used as emblems on tombstones symbolize eternal sleep. This symbolism was evoked in the children’s novel The Wonderful Wizard of Oz, in which a magical poppy field threatened to make the protagonists sleep forever.^[4]

A second interpretation of poppies in Classical mythology is that the bright scarlet colour signifies a promise of resurrection after death.^[5]

The poppy of wartime remembrance is Papaver rhoeas, the red-flowered corn poppy. This poppy is a common weed in Europe and is found in many locations; including Flanders, which is the setting of the famous poem “In Flanders Fields,” by the Canadian surgeon and soldier John McCrae. In Canada, the United Kingdom, Australia, South Africa and New Zealand, artificial poppies (plastic in Canada, paper in the UK, Australia, South Africa, Malta and New Zealand) are worn to commemorate those who died in war. This form of commemoration is associated with Remembrance Day, which falls on November 11. In Canada, Australia and the UK, poppies are often worn from the beginning of November through to the 11th, or Remembrance Sunday if that falls on a later date. In New Zealand and Australia, soldiers are commemorated on ANZAC day (April 25),^[6] although the poppy is still commonly worn around Remembrance Day. Wearing of poppies has been a custom since 1924 in the United States. Miss Moina Michael of Georgia is credited as the founder of the Memorial Poppy in the United States.^[7][8][9]

Ancient Egyptian doctors would have their patients eat seeds from a poppy to relieve pain. Poppy seeds contain small quantities of both morphine and codeine,^[10] which are pain-relieving drugs that are still used today. Poppy seeds and fixed oils can also be nonnarcotic because when they are harvested the morphine practically disappears from the seeds twenty days after the flower has opened (Jonsson and Krzymanski, 1989).

Other uses

The California poppy, Eschscholzia californica, is the state flower of California.

In Mexico, Grupo Modelo, the makers of Corona beer, used red poppy flowers in most of its advertising images until the 1960s.

A poppy flower is depicted on the reverse of the Macedonian 500 denars banknote, issued in 1996 and 2003.^[11] The poppy is also part of the coat of arms of the Republic of Macedonia.

Sunflower

Sunflowers make up the genus Helianthus. In Greek, helios means sun and anthos means flower, thus Sunflower. The genus, which contains about 67 species, is thought to be native to the Americas (North, South) originally, and were domesticated around 1000 B.C. Although, Sunflowers are now distributed almost worldwide.

The large, solitary Sunflower blossom, sometimes as large as a meter in diameter, is composed of yellow ray flowers and a central disk.n The Central disk is composed of either yellow, brown, or purple flowers, depending on the species. The flower is actually a head (formerly composite flower) of numerous flowers crowded together. The outer flowers on the Sunflower are the ray florets and can be yellow, maroon, orange, or other colors. These flowers are sterile. The flowers that fill the circular head inside the ray flowers are called disc florets.

Sunflower plants are cultivated in Sunflower farms for their seeds. Refined Sunflower-seed oil is edible, sunflowers have 39 to 49% oil in the seed. Sunflower seed accounts for about 14% of the world production of seed oils (6.9 million metric tons in 1985-86) and about 7% of the oilcake and meal produced from oilseeds. Sunflower oil is generally considered a premium oil because of its light color, high level of unsaturated fatty acids and lack of linolenic acid, bland flavor and high smoke points. Sunflower is the preferred and the most commonly used oil.

Facts About Sunflower

• Sunflower is the national flower of Russia and the state flower of Kansas, USA.
• Sunflower is notable for turning to face the Sun, a behavior known as heliotropism.
• Sunflowers were cultivated by Native Americans well over 1000 years ago.
• Sunflower heads consist of 1,000 to 2,000 individual flowers joined together by a receptacle base. The large petals around the edge of a sunflower head are individual ray flowers which do not develop into seed.
• Sunflower seeds have lots of calcium and 11 other important minerals. They do have 50% fat, but it is mostly polyunsaturated linoleic acid.
• Wild Sunflower is highly branched with small heads and small seeds, in contrast to the single-stem and large seed head of domesticated sunflower. Sunflower perfumes are also popular.
• According to the 1996 Guiness Book of Records, the tallest Sunflower ever grown measured 25 feet 5 and 1/2 inches. According to the 1996 Guiness Book of Records, the smallest sunflower ever grown to maturity measured 2 and 1/5 inches. According to the 1996 Guiness Book of Records, the largest sunflower head measured 32 and 1/4 inches across.
• The Modern Sunflower Kitchens have a large number of sunflower decorated items like sunflower painted crockery, Dinner sets, and living rooms with sunflower wallpaper, S. wallpaper art, S. Wallpaper borders, Sunflower rugs, Sunflower pillows.
• Golden mini Sunflowers herald sunny summer days. The carefree sunflower bouquet sends cheery wishes for all those special occasions – birthday, wedding anniversary, new baby, get well, or to simply say thanks.

 

Food Uses of Sunflower

The edible sunflower seeds can be eaten raw, cooked, roasted, or dried and ground for use in bread or cakes, as a snack. The seeds and the roasted seed shells have been used as a coffee substitute. Oil can be extracted and used for cooking and soap making. Yellow dyes have been made from the flowers, and black dyes from the seeds. The residue oil cake has been used as cattle and poultry feed, and high quality silage can be made from the whole plant. The buoyant pith of the stalk has been used in the making of life preservers.

Growing Sunflowers

 

Sunflowers do best in soil with lots of water holding capacity, drainage and fertilzer. Sunflower roots grow deep and spread a lot, so they can stand a dryspell every now and then. You should not over water a sunflower 20 days before and 20 days after flowering. This might deform the flower heads. If you really want your sunflower to do well, do soil tests. Too high nitrogen is not good, and make sure you have potassium and phosphorus in the soil.

• Start by planting seeds in damp soil 1-2″ deep.
• Seeds should be space 12 inches apart in rows that are 2 to 2 1/2 feet apart.
• If you want your sunflower to have a large head, space further apart and scatter them around the garden.
• They usually start to appear within a two week time frame.
• They should be completely grown in 80-90 days.

Sunflower Plant Care

• Weed control should usually be done by hand-weeding or with the use of herbicides to avoid damging shallow roots.
• Fertilization should be based on the results of a soil test. In the absence of a soil test, apply a complete fertilizer such as 8-8-8 or 10-10-10 at the rate of 1 to 2 pounds per 100 square feet of bed area just before new shoots emerge in the early spring.
• Avoid touching any emerging leaves with fertilizer to avoid leaf damage.
• Many newly planted perennials will not bloom the first year. A few, such as peonies, may take several years to bloom heavily.
• Many perennials should be staked to prevent them from bending or falling over during wind and rain. When staking is done correctly, the plants grow to cover the stakes.
• Remove old flowers to encourage rebloom on perennials. Many perennials should be cut back to ground level after blooming is finished to encourage new leaf growth from the base.
• Remove dead foliage and stems in the fall, and mulch to protect crowns and roots from alternating mild and freezing weather.
• Most perennials eventually become overcrowded and require division. Many perennials are also easily propagated in this way. Other methods of propagating perennials include stem cuttings, root cuttings and seed.
