_____________________

Tropaeolum /trɵˈpiːələm/, commonly known as nasturtium (/næˈstɜrʃ(i)əm/; literally “nose-twister” or “nose-tweaker”), is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus and is the only genus in the family Tropaeolaceae. The nasturtiums received their common name because they produce an oil that is similar to that of watercress (Nasturtium officinale).

The genus Tropaeolum, native to South and Central America, includes several very popular garden plants, the most commonly grown being T. majus, T. peregrinum and T. speciosum. One of the hardiest species is T. polyphyllum from Chile, the perennial roots of which can survive the winter underground at altitudes of 3,300 metres (10,000 ft).

Plants in this genus have showy, often intensely bright flowers, and rounded, peltate (shield-shaped) leaves with the petiole in the centre. The flowers are bisexual and zygomorphic, with five petals, a superior three-carpelled ovary, and a funnel-shaped nectar spur at the back, formed by modification of one of the five sepals.

History

The first Tropaeolum species was imported into Spain by the Spanish botanist Nicolás Monardes. He published an account in 1569 entitled Joyful News out of the Newe Founde Worlde in which he described, among other things, the plants and animals discovered in South America. The English herbalist John Gerard reports having received seeds of the plant from Europe in his 1597 book Herball, or Generall Historie of Plantes. Tropaeolum majus was named by the Swedish botanist Carl Linnaeus, who chose the genus name because the plant reminded him of an ancient custom. After victory in battle, the Romans used to set up a trophy pole called a tropaeum (from the Greek tropaion, source of English “trophy“). On this the armour and weapons of the vanquished foe were hung. Linnaeus was reminded of this by the plant as the round leaves resembled shields and the flowers, blood-stained helmets.

Nasturtiums were once known commonly as “Indian cresses” because they were introduced from the Americas, known popularly then as the Indies, and used like cress as salad ingredients. John Gerard called the plant “Indian Cresses” in his herbal. He wrote: “unto the backe part (of the flower) doth hange a taile or spurre, such as hath the Larkes heele, called in Latine Consolida regalis. He was comparing the flowers of Indian cress to those of forking larkspur (Consolida regalis) of the buttercup family. J R R Tolkien commented that an alternative anglicization of the name was “nasturtian” rather than “nasturtium”.

Description

Tropaeolum is a genus of dicotyledonous annual or perennial plants, often with somewhat succulent stems and sometimes tuberous roots. The alternate leaves are hairless, peltate and entire or palmately lobed. The petioles or leaf stalks are long and in many species are able to twine round other stems to provide support. The flowers are bisexual and showy, set singly on long stalks in the axils of the leaves. They have five sepals, the uppermost of which is elongated into a nectar spur. The five petals are clawed, with the lower three unlike the upper two. The eight stamens are in two whorls of unequal length and the superior ovary has three segments and three stigmas on a single style. The fruit is naked and nut-like, with three single seed segments.

Tropaeolum tuberosum

The most common flower in cultivation is a hybrid of T. majus, T. minus and T. peltophorum, and is commonly known as the nasturtium (and occasionally anglicized as nasturtian). It is mostly grown from seed as a half-hardy annual and both single and double varieties are available. It comes in a range of forms and colours including cream, yellow, orange and red, solid in colour or striped and often with a dark blotch at the base of the petals. It is vigorous and easily grown and does well in sun. It thrives in poor soil and dry conditions, whereas in rich soil it tends to produce much leafy growth and few flowers. Some varieties adopt a bush form while others scramble over and through other plants and are useful for planting in awkward spots or for covering fences and trellises.

The following cultivars have gained the Royal Horticultural Society‘s Award of Garden Merit:

• ‘Alaska Series’
• ‘Hermine Grashoff’
• ‘Whirlybird Series’

The blue nasturtium (Tropaeolum azureum) is a tender species from Chile which has violet-blue flowers with white eyes that can be as much as 4 cm (1.6 in) across

Tropaeolum brachyceras has 2.5 cm (1 in) yellow flowers with purplish markings on wiry, climbing stems. It is a half hardy perennial from Chile and may remain dormant for several years before being sparked into growth by some unknown trigger factor.

Tropaeolum hookerianum is a tuberous-rooted species from Chile. There are two subspecies, T. h. austropurpureum which has violet-purple flowers and T. h. pilosum with yellow flowers.

The Canary creeper (Tropaeolum peregrinum) is a trailing and climbing half-hardy annual species with wiry stalks and palmately lobed leaves. The pale yellow, fringed flowers are borne on long stalks. It originated from Peru but may first have been cultivated in the Canary Islands before being introduced into Western Europe.

Wreath nasturtium (Tropaeolum polyphyllum) is a prostrate plant originating from Argentina and Chile. It has silvery, deeply lobed leaves and a profusion of small, bright yellow flowers on long trailing stalks. After flowering, the plant dies back. It is a perennial with underground rhizomes which send up new shoots at intervals. In a suitable sunny location with well drained soil, it will survive for several years. It is a very hardy species; the tubers can grow at depths of 60 cm (24 in) enabling the plant to survive at altitudes of as much as 3,300 metres (10,000 ft) in the Andes.

The flame flower (Tropaeolum speciosum) is well adapted to cool, moist climates and notoriously does well in Scotland. It sends up shoots which thread their way through hedges and shrubs and which, when they emerge into the light, bear brilliant red flowers among small, five or six-lobed leaves. It is difficult to establish but is an attractive garden plant when it thrives. This plant has gained the Royal Horticultural Society’s Award of Garden Merit.

Three-coloured Indian cress (Tropaeolum tricolor) is another tuberous, climbing species grown for its attractive red, purple and yellow tubular flowers. It comes from Chile and Bolivia and is a reliable winter-growing species.

Mashua (Tropaeolum tuberosum) is a perennial climbing plant from the Andes grown for its tuberous roots. It has been cultivated since ancient times and depictions of it are found at archaeological sites pre-dating the Incas. It has leaves with five to seven lobes and small, long-spurred, red and yellow flowers. The tubers have an unpleasant smell when raw which disappears on cooking. It is frost-hardy and produces crops of 30 tons per hectare at a height of 3,000 metres (9,800 ft) above sea level. The cultivar T. tuberosum lineamaculatum ‘Ken Aslet’ has gained the Royal Horticultural Society’s Award of Garden Merit.

Species that originated from the coastal areas and from the lower foothills make most of their growth in winter whereas the true alpine species are summer growers. Tuberous Tropaeolum species are well known for occasionally remaining dormant for one or more years. The species with underground rhizomes and tubers can be propagated from these while other species are best raised from seed. Fresh seed is favoured by many growers but dried seed is also often successful. Seed from the winter growing species should be sown in the autumn while the summer growing species are best sown in the spring in well-drained compost and covered with 1 to 2 cm (0.4 to 0.8 in) of grit or sand. The containers should be kept at below 4 °C (39 °F) until the seedlings appear in about a month, as too high a temperature inhibits germination.

Uses

Culinary

All parts of T. majus are edible. The flower has most often been consumed, making for an especially ornamental salad ingredient; it has a slightly peppery taste reminiscent of watercress, and is also used in stir fry. The flowers contain about 130 mg vitamin C per 100 grams (3.5 oz)^] about the same amount as is contained in parsley.

Moreover, they contain up to 45 mg of lutein per 100 gr, which is the highest amount found in any edible plant. The unripe seed pods can be harvested and dropped into spiced vinegar to produce a condiment and garnish, sometimes used in place of capers.

Mashua (T. tuberosum) produces an edible underground tuber that is a major food source in parts of the Andes.

Herbal medicine

Nasturtiums have been used in herbal medicine for their antiseptic and expectorant qualities. They are said to be good for chest colds and to promote the formation of new blood cells. T. majus has been used in herbal medicine for respiratory and urinary tract infections.

Taxonomy

Tropaeolum was previously placed in the family Tropaeolaceae along with two other genera, Magallan and Trophaeastrum. The monotypic genus Magallan was characterised by having winged fruit, and the two species of Trophaeastrum lacked spurs. The genus Tropaeolum was diagnosed only by the absence of the characteristics of the other two genera. A molecular study undertaken in 2000 found Tropaeolum to be paraphyletic when the other two genera are segregated, so Magallan and Trophaeastrum were reduced to synonyms of Tropaeolum. Tropaeolaceae was thus rendered monogeneric, a family of only one genus.

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.

Ranunculus – Buttercup etc.

Ranunculus /ræˈnʌŋkjʊləs/is a large genus of about 600 species of plants in the Ranunculaceae. Members of the genus include the buttercups, spearworts, water crowfoots and the lesser celandine.

Scientific classification
Kingdom: Plantae
(unranked): Angiosperms
(unranked): Eudicots
Order: Ranunculales
Family: Ranunculaceae
Genus: Ranunculus

They are mostly herbaceous perennials with bright yellow or white flowers (if white, still with a yellow centre); some are annuals or biennials. A few species have orange or red flowers. There are usually five petals, but sometimes six, numerous, or none, as in R. auricomus. The petals are often highly lustrous, especially in yellow species. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds.

The Water crowfoots (Ranunculus subgenus Batrachium), which grow in still or running water, are sometimes treated in a separate genus Batrachium (from Greek batrachos βάτραχος: frog, etymology comparable to ranunculus itself). They have two different leaf types, thread-like leaves underwater and broader floating leaves. In some species, such as R. aquatilis, a third, intermediate leaf type occurs.

Ranunculus species are used as food plants by the larvae of some Lepidoptera species including Hebrew Character and Small Angle Shades. Some species are popular ornamental flowers in horticulture, with many cultivars selected for large and brightly coloured flowers

Naming

The name Ranunculus is Late Latin for “little frog,” from rana “frog” and a diminutive ending. This probably refers to many species being found near water, like frogs.

The name buttercup may derive from a false belief that the plants give butter its characteristic yellow hue (in fact it is poisonous to cows and other livestock). A popular children’s game involves holding a buttercup up to the chin; a yellow reflection is supposed to indicate fondness for butter.

In the interior of the Pacific Northwest of the United States the buttercup is called “Coyote’s eyes” — ʔiceyéeyenm sílu in Nez Perce and spilyaynmí áčaš in Sahaptin. In the legend Coyote was tossing his eyes up in the air and catching them again when Eagle snatched them. Unable to see, Coyote made eyes from the buttercup.^{[citation needed]}

Splitting of the genus

Molecular investigation of the genus has revealed that Ranunculus is not monophyletic with respect to a number of other recognized genera in the family – e.g. Ceratocephala, Halerpestes, Hamadryas, Laccopetalum, Myosurus, Oxygraphis, Paroxygraphis and Trautvetteria. A proposal to split Ranunculus into several genera have thus been published in a new classification for the tribe Ranunculeae. The split (and often re-recognized) genera include Arcteranthis Greene, Beckwithia Jeps., Callianthemoides Tamura, Coptidium (Prantl) Beurl. ex Rydb., Cyrtorhyncha Nutt. ex Torr. & A.Gray, Ficaria Guett., Krapfia DC., Kumlienia E.Greene and Peltocalathos Tamura.

Toxicity

All Ranunculus species are poisonous when eaten fresh by cattle, horses, and other livestock, but their acrid taste and the blistering of the mouth caused by their poison means they are usually left uneaten. Poisoning can occur where buttercups are abundant in overgrazed fields where little other edible plant growth is left, and the animals eat them out of desperation. Symptoms include bloody diarrhea, excessive salivation, colic, and severe blistering of the mucous membranes and gastrointestinal tract. When Ranunculus plants are handled, naturally occurring ranunculin is broken down to form protoanemonin, which is known to cause contact dermatitis in humans and care should therefore be exercised in extensive handling of the plants.    The toxins are degraded by drying, so hay containing dried buttercups is safe.

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.

The name ‘clematis’ is derived from the Greek word klema, meaning vine branch or vine-like. It is possible that even before the use of the word ‘Klema-tis’ the whole genus was known as atragene, meaning ‘firecracker’ in Greek. Apparently, when large dry stems of C. vitalba are placed in a fire, the heat causes them to split, making a noise like firecrackers. more History Of Clematis
