Taraxacum officinale, the common dandelion (often simply called dandelion), is a flowering herbaceous perennial plant of the family Asteraceae (Compositae). It can be found growing in temperate regions of the world, in lawns, on roadsides, on disturbed banks and shores of water ways, and other areas with moist soils. T. officinale is considered a weed, especially in lawns and along roadsides, but it is sometimes used as a medical herb and in food preparation. Common dandelion is well known for its yellow flower heads that turn into round balls of silver tufted fruits that disperse in the wind called “blowballs”[3] or “clocks” (in both British and American English).

Species: T. officinale

Description

Taraxacum officinale grows from generally unbranched taproots and produces one to more than ten stems that are typically 5 to 40 cm tall, but sometimes up to 70 cm tall. The stems can be tinted purplish, they are upright or lax, and produce flower heads that are held as tall or taller than the foliage. The foliage may be upright-growing or horizontally spreading; the leaves have petioles that are either unwinged or narrowly winged. The stems can be glabrous or sparsely covered with short hairs. Plants have milky latex and the leaves are all basal; each flowering stem lacks bracts and has one single flower head. The yellow flower heads lack receptacle bracts and all the flowers, which are called florets, are ligulate and bisexual. The fruits are mostly produced by apomixis.

The leaves are 5 to 45 cm long and 1 to 10 cm wide, and are oblanceolate, oblong, or obovate in shape, with the bases gradually narrowing to the petiole. The leaf margins are typically shallowly lobed to deeply lobed and often lacerate or toothed with sharp or dull teeth.

The calyculi (the cuplike bracts that hold the florets) are composed of 12 to 18 segments: each segment is reflexed and sometimes glaucous. The lanceolate shaped bractlets are in two series, with the apices acuminate in shape. The 14- to 25-mm wide involucres are green to dark green or brownish-green, with the tips dark gray or purplish. The florets number 40 to over 100 per head, having corollas that are yellow or orange-yellow in color.490247946_641d89acc0_z

The fruits, called cypselae, range in color from olive-green or olive-brown to straw-colored to grayish, they are oblanceoloid in shape and 2 to 3 mm long with slender beaks. The fruits have 4 to 12 ribs that have sharp edges. The silky pappi, which form the parachutes, are white to silver-white in color and around 6 mm wide. Plants typically have 24 or 40 pairs of chromosomes but some plants have 16 or 32 chromosomes.

Taxonomy

The taxonomy of the genus Taraxacum is complicated by apomictic and polyploid lineages, and the taxonomy and nomenclatural situation of Taraxacum officinale is not yet fully resolved, The taxonomy of this species has in the past been complicated by the recognition of numerous species, subspecies and microspecies. E.g. Rothmaler’s flora of Germany recognizes roughly 70 microspecies.The plants introduced to North America are triploids that reproduce by obligate gametophytic apomixis Some authorities recognize three subspecies of Taraxacum officinale including:

  • Taraxacum officinale ssp. ceratophorum (Ledeb.) Schinz ex Thellung which is commonly called common dandelion, fleshy dandelion, horned dandelion or rough dandelion. It is native to Canada and the western US. Some sources list it as a species, Taraxacum ceratophorum.
  • Taraxacum officinale ssp. officinale, which is commonly called common dandelion or wandering dandelion.
  • Taraxacum officinale ssp. vulgare (Lam.) Schinz & R. Keller, which is commonly called common dandelion.

573193995_3d076fa188_zTwo of them have been introduced and established in Alaska and the third (ssp. ceratophorum ) is native there.

Taraxacum officinale has many English common names (of which some are no longer in use), including blowball, lion’s-tooth, cankerwort, milk-witch, yellow-gowan, Irish daisy, monks-head, priest’s-crown and puff-ball; other common names include, faceclock, pee-a-bed, wet-a-bed,  swine’s snout,  white endive, and wild endive.

Carl Linnaeus named the species Leontodon Taraxacum in 1753. The genus name Taraxacum, might be from the Arabic word “Tharakhchakon“, or from the Greek word “Tarraxos“. The common name “dandelion,” comes from the French phrase “dent de lion” which means “lion’s tooth”, in reference to the jagged shaped foliage.

Ecology

Taraxacum officinale is native to Eurasia, and now is naturalized throughout North America, southern Africa, South America, New Zealand, Australia, and India. It occurs in all 50 states of the USA and most Canadian provinces. It is considered a noxious weed in some jurisdictions, and is considered to be a nuisance in residential and recreational lawns in North America. It is also an important weed in agriculture and causes significant economic damage because of its infestation in many crops worldwide.

The dandelion is a common colonizer of disturbed habitats, both from wind blown seeds and seed germination from the seed bank. The seeds remain viable in the seed bank for many years, with one study showing germination after nine years. This species is a somewhat prolific seed producer, with 54 to 172 seeds produced per head, and a single plant can produce more than 5,000 seeds a year. It is estimated that more than 97,000,000 seeds/hectare could be produced yearly by a dense stand of dandelions When released, the seeds can be spread by the wind up to several hundred meters from their source. The seeds are also a common contaminant in crop and forage seeds. The plants are adaptable to most soils and the seeds are not dependent on cold temperatures before they will germinate but they need to be within the top 2.5 centimeters of soil.

While not in bloom, this species is sometimes confused with others, such as Chondrilla juncea, that have similar basal rosettes of foliage.  Another plant, sometimes referred to as Fall Dandelion, is very similar to dandelion, but produces “yellow fields” later.

While the dandelion is considered a weed by many gardeners and lawn owners, the plant has several culinary and medicinal uses. The specific name officinalis refers to its value as a medicinal herb, and is derived from the word opificina, later officina, meaning a workshop or pharmacy. The flowers are used to make dandelion wine, the greens are used in salads, the roots have been used to make a coffee substitute (when baked and ground into powder) and the plant was used by Native Americans as a food and medicine.

Culinary

Dandelions are wildcrafted or grown on a small scale as a leaf vegetable. The leaves (called dandelion greens) can be eaten cooked or raw in various forms, such as in soup or salad. They are probably closest in character to mustard greens. Usually the young leaves and unopened buds are eaten raw in salads, while older leaves are cooked. Raw leaves have a slightly bitter taste. Dandelion salad is often accompanied with hard boiled eggs. The leaves are high in vitamin A, vitamin C and iron, carrying more iron and calcium than spinach.

Dandelion flowers can be used to make dandelion wine, for which there are many recipes. Most of these are more accurately described as “dandelion-flavored wine,” as some other sort of fermented juice or extract serves as the main ingredient. It has also been used in a saison ale called Pissenlit (literally “wet the bed” in French) made by Brasserie Fantôme in Belgium. Dandelion and burdock is a soft drink that has long been popular in the United Kingdom.

Another recipe using the plant is dandelion flower jam. In Silesia and also other parts of Poland and world, dandelion flowers are used to make a honey substitute syrup with added lemon (so-called May-honey). This “honey” is believed to have a medicinal value, in particular against liver problems. Ground roasted dandelion root can be used as a non-caffeinated coffee substitute.

Herbal medicine

Dandelion root medicinally is sold primarily  as a diuretic.  A hepatoprotective effect in mice of chemicals extracted from dandelion root has been reported.Dandelion is used in herbal medicine as a mild laxative, for increasing appetite, and for improving digestion. The milky latex has been used as a mosquito repellent and as a folk remedy to treat warts.

Other

Yellow or green dye colours can be obtained from the flowers but little colour can be obtained from the roots of the plant.

T. officinale is food for the caterpillars of several Lepidoptera (butterflies and moths), such as the tortrix moth Celypha rufana. See also List of Lepidoptera that feed on dandelions.

Toxicity

Dandelion (Taraxacum officinale) has been linked to outbreaks of stringhalt in horses.

 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

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.

10511243_10152480624456067_4007012348158508553_nEcology

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:10436158_10152480624486067_266170351256251489_n

  • 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 ; 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:

野百合Lilium brownii, 百合(变种)Lilium brownii var. viridulum, 渥丹 Lilium concolor, 毛百合 Lilium dauricum, 川百合 Lilium davidii, 东北百合 Lilium distichum, 卷丹 Lilium lancifolium, 新疆百合(变种) Lilium martagon var. pilosiusculum, 山丹 Lilium pumilum, 南川百合 Lilium rosthornii, 药百合(变种) Lilium speciosum var. gloriosoides.

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.10529483_10152514701546067_1376675825_n

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.

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.Image

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]

Image

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

 

ImageUses

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).

Image

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]

Medical uses

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.

The powerful symbolism of Papaver rhoeas has been borrowed by various advocacy campaigns, such as the White Poppy and Simon Topping‘s black poppy.

The girl’s given name “Poppy” is taken from the name of the flower.[citation needed]

Poppies (called amapolas in Spanish) are commonly featured as the central flower in Puerto Rican weddings.[citation needed]

Artificial poppies (called “Buddy Poppies”) are used in the veterans’ aid campaign by the Veterans of Foreign Wars, which provides money to the veterans who assemble the poppies and various aid programs to veterans and their families.[12]

Canada issued special quarters (25-cent coins) with a red poppy on the reverse in 2004, 2008 and 2010. The 2004 Canadian “poppy” quarter was the world’s first coloured circulation coin.[13]

Family: Scrophulariaceae
Common names: Mauve nemesia (E)
Wildeleeubekkie (A)
nemesia 002 26_08_2007
Nemesia fruticans occurs naturally throughout the summer rainfall grassland areas of South Africa where it grows mostly in among rocks. Like many other grassland perennials it has a woody taproot that helps it survive fires and winter frost.
The flowers resemble little snapdragon flowers, with two lips and a spur. They are dusty-pink or mauve or even whiter in colour and decorated with bright yellow protuberances in the throat. The mauve nemesia flowers mostly at the beginning of spring (September-October), but the flowering season can extend through summer to autumn. The seeds are produced in flat capsules which are dry and whitish to yellow-brown in colour.

The genus Nemesia is found only in South Africa and has about seventy species. The family Scrophulariaceae is the large snapdragon family which consists of about 5 100 species worldwide. Amongst them, the foxgloves or Digitalis are known to contain certain drug chemicals. In South Africa there are 79 genera of the family Scrophulariaceae.


Growing Nemesia fruticans

Nemesia fruticans is used mostly as a flowering bedding plant and as an ornamental pot plant. Various colour forms are available from specialist nurseries.

It is best propagated by seed sown in March for summer flowering. It can also be propagated by means of cuttings. Cuttings are best taken in spring when regrowth commences and active root formation takes place. Special colour forms are best propagated from cuttings.

The mauve nemesia prefers well-drained soil, enriched with compost. It prefers to be planted in a sunny position. It can be treated as an annual and will self-seed if plants have been allowed to set seed before removal. Alternatively it can be treated as a perennial and cut back after flowering each year, or in early spring. It is frost tolerant. Although the upper growth is damaged by frost, the plant will resprout from the taproot.

Bidens is a genus of flowering plants in the aster family, Asteraceae. The common names beggarticks, black jack, burr marigolds, cobbler’s pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers refer to the fruits of the plants, most of which are bristly and barbed, with two sharp pappi at the end. The generic name refers to the same character; Bidens comes from the Latin bis (“two”) and dens (“tooth”).

Kingdom: Plantae

Order: Asterales
Family: Asteraceae
Subfamily: Asteroideae
Tribe: Coreopsideae
Genus: Bidens

Propagation

The plants are zoochorous; their seeds will stick to clothing, fur or feathers, and be carried to new habitat. This has enabled them to colonize a wide range, including many oceanic islands. Some of these species occur only in a very restricted range and several are now threatened with extinction, notably in the Hawaiian Islands. Due to the absence of native mammals on these islands, some of the oceanic island taxa have reduced burrs, evolving features that seem to aid in dispersal by the wind instead.

It is on the endangered list, so I do my bit by growing them (wildflower native to British Columbia) on my balcony hoping it will help reseed. It is native to British Columbia and other than that I don’t know too much, feel free to add via comments or email me.

Distribution

Bidens is distributed throughout the tropical and warm temperate regions of the world.Most species occur in the Americas, Africa, and Polynesia, and there are some in Europe and Asia. Bidens is closely related to the American genus Coreopsis, and the genera are sometimes difficult to tell apart; in addition, neither is monophyletic.

On the Hawaiian Islands, Bidens are called kokoʻolau or koʻokoʻolau.

Uses

Nodding beggarticks (B. cernua) and hairy beggarticks (B. pilosa) are useful as honey plants. Several Bidens species are used as food by the caterpillars of certain Lepidoptera, such as the noctuid moth Hypercompe hambletoni and the brush-footed butterfly Vanessa cardui, the Painted Lady. The Bidens mottle virus, a plant pathogen, was first isolated from B. pilosa, and it infects many other Asteraceae and plants of other families.

Diversity

The taxonomy of Bidens has been described as “chaotic”, and it is not clear how many taxa are included in its bounds. There are probably at least 150 to 250 species, and some estimates fall around 230.
