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.

Eruca sativa (syn. E. vesicaria subsp. sativa (Miller) Thell., Brassica eruca L.) is an edible annual plant, commonly known as salad rocket, roquette, rucola, rugula, colewort, and, in the United States, arugula. It is sometimes conflated with Diplotaxis tenuifolia, the perennial wall rocket, another plant of the Brassicaceae family, which in the past was used in the same manner. Eruca sativa, which is widely popular as a salad vegetable, is a species of Eruca native to the Mediterranean region, from Morocco and Portugal in the west to Syria, Lebanon and Turkey in the east.^] The Latin adjective sativa in the plant’s binomial is derived from satum, the supine of the verb sero, meaning “to sow”, indicating that the seeds of the plant were sown in gardens. Eruca sativa differs from E. vesicaria in having early deciduous sepals.^] Some botanists consider it a subspecies of Eruca vesicaria: E. vesicaria subsp. sativa. Still others do not differentiate between the two.

Other common names include garden rocket, or more simply rocket (British, Australian, Canadian, South African and New Zealand English), and eruca. The English common name, rocket, derives from the French roquette, a diminutive of the Latin word eruca, which designated an unspecified plant in the Brassicaceae family (probably a type of cabbage). Arugula, the common name now widespread in the United States, entered American English from non-standard (dialect) Italian. (The standard Italian word is rucola, a diminutive of the Latin “eruca”). The Oxford English Dictionary dates the first appearance of “arugula” in American English to a 1960 New York Times article by food editor and prolific cookbook writer, Craig Claiborne,

Eruca sativa grows 20–100 centimetres (8–39 in) in height. The leaves are deeply pinnately lobed with four to ten small lateral lobes and a large terminal lobe. The flowers are 2–4 cm (0.8–1.6 in) in diameter, arranged in a corymb in typical Brassicaceae fashion; with creamy white petals veined with purple, and with yellow stamens; the sepals are shed soon after the flower opens. The fruit is a siliqua (pod) 12–35 millimetres (0.5–1.4 in) long with an apical beak, and containing several seeds (which are edible). The species has a chromosome number of 2n = 22.

Ecology

Eruca sativa typically grows on dry, disturbed ground and is also used as a food by the larvae of some moth species, including the Garden Carpet moth. Eruca sativa roots are also susceptible to nematode infestation.

Cultivation and history

A pungent, leafy green vegetable resembling a longer-leaved and open lettuce, rocket is rich in vitamin C and potassium. In addition to the leaves, the flowers, young seed pods and mature seeds are all edible.

Grown as an edible herb in the Mediterranean area since Roman times, it was mentioned by various classical authors as an aphrodisiac, most famously in a poem long ascribed to Virgil, Moretum, which contains the line: “et veneris revocans eruca morantuem” (“the rocket excites the sexual desire of drowsy people”). Some writers assert that for this reason during the Middle Ages it was forbidden to grow rocket in monasteries. It was listed, however, in a decree by Charlemagne of 802 as one of the pot herbs suitable for growing in gardens.Gillian Reilly, author of the Oxford Companion to Italian Food, states that because of its reputation as a sexual stimulant, it was “prudently mixed with lettuce, which was the opposite” (i.e., calming or even soporific). Reilly continues that “nowadays rocket is enjoyed innocently in mixed salads, to which it adds a pleasing pungency”.

Rocket was traditionally collected in the wild or grown in home gardens along with such herbs as parsley and basil. It is now grown commercially from the Veneto to Iowa to Brazil, and is available for purchase in supermarkets and farmers’ markets throughout the world. It is also naturalised as a wild plant away from its native range in temperate regions around the world, including northern Europe and North America. In India, the mature seeds are known as Gargeer.

Growing rocket in mild frost conditions stymies the growth of the plant, as well as turning the green leaves red.

Uses

Rocket has a pungent, peppery flavor that is exceptionally strong for a leafy green. It is frequently used in salads, often mixed with other greens in a mesclun. It is also used raw with pasta or meats in northern Italy and in western Slovenia (especially in the Slovenian Istria). In Italy, raw rocket is often added to pizzas just before the baking period ends or immediately afterwards, so that it will not wilt in the heat. It is also used cooked in Puglia, in Southern Italy, to make the pasta dish cavatiéddi, “in which large amounts of coarsely chopped rocket are added to pasta seasoned with a homemade reduced tomato sauce and pecorino“ as well as in “many unpretentious recipes in which it is added, chopped, to sauces and cooked dishes” or in a sauce (made by frying it in olive oil and garlic) used a condiment for cold meats and fish. In the Slovenian Littoral, it is often combined with boiled potatoes, used in a soup, or served with the cheese burek, especially in the town of Koper.

A sweet, peppery digestive alcohol called rucolino is made from rocket on the island of Ischia in the Gulf of Naples. This liqueur is a local specialty enjoyed in small quantities following a meal in the same way as a limoncello or grappa.

In Brazil, where its use is widespread, rocket is eaten raw in salads. A popular combination is rocket mixed with mozzarella cheese (normally made out of buffalo milk) and sun-dried tomatoes.

In Egypt the plant is commonly eaten raw as a side dish with many meals, with ful medames for breakfast, and regularly accompanies local seafood dishes.

In West Asia and Northern India, Eruca seeds are pressed to make taramira oil, used in pickling and (after aging to remove acridity) as a salad or cooking oil. The seed cake is also used as animal feed.

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.

About Gardenia Flower and Plant

Gardenias are very fragrant creamy-white flowers with glossy, dark-green leaves. Gardenia flowers are solitary or in small clusters, white or pale yellow. The gardenia flowers are with a tubular-based corolla with 5-12 lobes petals from 5-12 cm diameter.

Gardenia plants are evergreen shrubs and small trees growing to 1-15 m tall. The Gardenia plant leaves are opposite or in whorls of three or four. They are dark green and glossy 5-50 cm long and 3-25 cm broad, with a leathery texture. They are simple, entire, hairless, with wavy margin.

 

Growing Gardenias

• Gardenia plants need high humidity.
• A loose, well-drained organic soil is recommended.
• For best results plant gardenias in full sun, partial shade, or shifting shade.
• Dig a hole twice the size of the root ball.
• Thoroughly mix one part soil and one part planting mix.
• Check that the top of the original root ball is slightly above the level of the surrounding soil.
• Take the soil mixture and make a gentle mound of soil sloping away from the plant so that the water drains away from the trunk.
• Remove any air pockets, if present.
• Water the plant with a root stimulator.

Gardenia Care

• Do not over-water gardenias.
• Fertilize with an acid fertilizer.
• Check for aphids, mealybugs, spider mites, thrips and scales.
• Also check gardenia plants for bud drop, a common ailment.

Sweet Pea

Did you know? Currently, almost every cultivar of the sweet pea is available in international markets, except yellow.

 

Sweet pea is a plant native to the Mediterranean region. Since they are annual climbers and grow in a wide spectrum of colors, they grow for a long period of time, and are the first choice for individual cut flowers and/or exquisite floral decorations.

Kingdom – Plantae

Division – Magnoliophyta

Class – Magnoliopsida

Order – Fabales

Family – Fabaceae

Subfamily – Faboideae

Tribe – Vicieae

Genus – Lathyrus

Species – odoratus

All sweet pea flower varieties are not fragrant, but the ones that are, live up to their namesake. This particular strain of flowers contains up to 160 species.

One must keep a constant eye on the flower throughout its lifespan, as it is prone to all kinds of pests and insects. Unlike the edible pea, seeds of this flower are not edible, and are known to cause toxicity.

Growing Sweet Peas

•  Choose a site in full sun with rich, well-drained soil.
• Sweet Pea vines need full sun and rich, well drained soil.
• Work in some compost before planting. Sweet Pea seeds should be sown directly where it is to grow.
• Soak seeds overnight then plant about an inch deep and 3-4 inches apart.
• Water thoroughly after planting, then restrict water until seeds germinate.
• Fertilize every two to four weeks, or work in a slow-release fertilizer at planting time. Sweet peas are heavy feeders.
• The Sweet Pea plant benefits from deadheading, but leave a few flowers at the end of theseason to seed for next year.

Sweet Pea Plant Care

• Plant Sweet Peas in an area that gets good air circulation.
• Water early in the day so the leaves are dry by nightfall; wet leaves are a magnet for fungus.
• Do not over fertilize or you’ll wind up with very deep green leaves but few flowers.
• Alternatively,organic fertilizers are also excellent for Sweet Peas. Additional mulching with composted manure will help retain soil moisture and provide nutrients for strong plant growth and flowering.
• If the blooms are not cut regularly, deadhead the plant as soon as flowers fade. Allowing the plant to produce seedpods will reduce overall flower production.
• Removing spent blooms will ensure more blooms.
• Do not grow sweet peas where other legumes are growing or grew last year.

Gifting Tip

Sweet Pea is the most popular gifting option world over, but don’t let this deter you into thinking that it will be a common gifting idea. Due to its availability in numerous colors and its ability to be styled into any kind of floral arrangement, it has immense scope for original, innovative arrangements every time.
