Botanical Name :Trillium erectum
Family: Melanthiaceae
Genus: Trillium
Species: T. erectum
Kingdom: Plantae
Order: Liliales

Common Names: Wake-robin, Red trillium, Purple trillium, Beth root, or stinking Benjamin

Habitat :Trillium erectum is native to the east and north-east of North America. – Quebec to Ontario and Michigan, south to Tennessee. It grows in cool, rich, moist, neutral to acidic soils of upland deciduous forests, mixed deciduous-coniferous forests, coniferous swamp borders at elevations of 200 – 700 metres.

Description:
Trillium erectum is a Spring ephemeral, an herbaceous perennial plant whose life-cycle is synchronised with that of the deciduous forests where it lives.

This plant grows to about 40 cm (16 in) in height with a spread of 30 cm (12 in), and can tolerate extreme cold in winter, surviving temperatures down to -35 °C (-31 °F). Like all trilliums, its parts are in groups of three, with 3-petalled flowers above whorls of pointed triple leaves. The leaves contain calcium oxalate crystals and crystal raphide, and should not be consumed by humans. The flowers are a deep red colour, though there is a white form. The flowers have the smell of rotting meat, as they are pollinated by flies.

The plant takes its name “wake-robin” by analogy with the Robin, which has a red breast heralding spring.

This plant has gained the Royal Horticultural Society‘s Award of Garden Merit.

Cultivation:
Landscape Uses:Border, Ground cover, Woodland garden. Prefers a deep well-drained woodland or humus-rich soil in a somewhat shady position that remains moist in the summer. Prefers a neutral to slightly acid soil. Grows well in open deciduous woodland. Succeeds in a sunny position if the soil does not dry out. Succeeds in deep shade. A very hardy plant. Plants are long-lived. Any transplanting is best done whilst the plants are in flower. A very variable species, it is subject to mutation. Members of this genus are rarely if ever troubled by browsing deer or rabbits, though slugs are very fond of the leaves. The flowers have an unattractive smell rather like putrefied flesh. The white-flowered form, blandum, is almost scentless. Plants can flower in two years from seed. Special Features:Attractive foliage, North American native, Naturalizing, Flowers have an unpleasant odor.

Propagation:
Seed – best sown in a shaded cold frame as soon as it is ripe. Stored seed should be sown in late winter or early spring. Seed usually germinates within 1 – 3 months at 15°c. Another report says that seeds produce a root after the first cold stratification but no shoot is produced until after a second winter, whilst yet another report says that the seed can take 3 years to germinate. The seedlings are prone to damp off and must therefore be watered with care and given plenty of fresh air. The young plants need to be overwintered in a cold frame for the first year and can then be planted out in late spring. It is very important that the pots become neither too dry nor too wet. Division with care when the plants die down after flowering. Larger divisions can be planted out direct into their permanent positions.

Edible Uses: Leaves – raw or cooked. Used in spring, the young unfolding leaves are an excellent addition to the salad bowl, tasting somewhat like sunflower seeds. Leaves can also be cooked as a potherb.

Parts Used: root

Constituents: saponins

Medicinal Uses:

Properties: * Anodyne * emetic * Expectorant

* Cough * Menopause

Beth root was traditionally used by various native North American Indian tribes as a woman’s herb to aid childbirth, as a treatment for irregular menstrual periods, period pains and excessive vaginal discharge. Modern research has shown that the root contains steroidal saponins, which have hormonal effects on the bod. These saponins are being used in gynaecological and obstetric medicine. This herb should not be taken during pregnancy except under professional supervision. The root is antiseptic, aphrodisiac, astringent, expectorant, tonic, uterine toni. It is used internally in the treatment of a wide range of women’s complaints including haemorrhage from the uterus, urinary tract and lungs, and also to curb excessive menstruation. It has proved to be of value in stopping bleeding after parturition. Externally, it is used to treat excessive vaginal discharge, ulcers (especially varicose), skin complaints, gangrene, insect bites and stings. It is also used as a wash for sore nipples. The root is harvested in late summer, after the leaves have died down, and is dried for later use. The whole plant is used as a poultice for tumours, inflammations and ulcers

It was also used to as a parturition herb. 1 Beth root was used in early American cough and cold syrups as an expectorant. The saponins in beth root have been used as an industrial source for the pharmaceutical industry. While Beth root certainly has some good medicinal qualities, this species is considered to be endangered and should be conserved and not wildcrafted for use on a commercial basis.

Known Hazards: Can cause nausea in high doses and promote labour and menstruation. Local application can cause irritation. Should not be used during pregnancy

Echinacea purpurea

Botanical name :Echinacea purpurea
Family: Asteraceae
Tribe: Heliantheae
Genus: Echinacea
Species: E. purpurea
Kingdom: Plantae
Order: Asterales

Synonyms : Brauneria purpurea. Echinacea intermedia. Echinacea serotina. Rudbeckia purpurea.

Common Names: Echinacea, Eastern purple coneflower, Hedge Coneflower, Black Sampson , Purple Coneflower

Habitat : Echinacea purpurea is native to North America and it extends through the Great Plains from Michigan all the way down to northern Texas and Georgia. It grows in dry open woods, prairies and barrens

Description :
Echinacea purpurea is a herbaceous perennial plant. It is 120 cm (47 in) tall by 50 cm (20 in) wide at maturity. Depending on the climate, it blooms throughout spring and summer. Its individual flowers (florets) within the flower head are hermaphroditic, having both male and female organs on each flower. It is pollinated by butterflies and bees. Its habitats include dry open woods, prairies and barrens, as well as cultivated beds. Although the plant prefers loamy or sandy, well-drained soils, it is little affected by the soil’s pH.

A popular perennial with smooth, 2-5 ft. stems and long-lasting, lavender flowers. Rough, scattered leaves that become small toward the top of the stem. Flowers occur singly atop the stems and have domed, purplish-brown, spiny centers and drooping, lavender rays. An attractive perennial with purple (rarely white), drooping rays surrounding a spiny, brownish central disk.

Cultivation:
E. purpurea is also grown as an ornamental plant, and numerous cultivars have been developed for flower quality and plant form.Unable to grow in the shade, it thrives in either dry or moist soil and can tolerate drought once established. The following have gained the Royal Horticultural Society‘s Award of Garden Merit:-

*’Magnus’

*’Rubinstein’

*’Ruby Giant’

Propagation:
It can be propagated either vegetatively or from seeds. Useful vegetative techniques include division, root cuttings, and basal cuttings. Clumps can be divided, or broken into smaller bunches, which is normally done in the spring or autumn. Cuttings made from roots that are “pencil-sized” will develop into plants when started in late autumn or early winter. Cuttings of basal shoots in the spring may be rooted when treated with rooting hormones.

Medicinal Uses:
Preparations of this plant were used by the Plain Indians (Comanche and Sioux) for the treatment of upper respiratory infections, burns, snakebites, and cancers. The European settlers learned about these indications from the Indians. It has been demonstrated that plant extracts stimulate the immune system to combat bacterial and viral infections. It also possesses antibiotic properties. Echinacea’s name is derived from the Greek word for hedgehog and was inspired by the appearance of the flower’s central cone.

Echinacea should be of particular interest during the cold and flu season when you are exposed to these illnesses on a regular basis. When used correctly it is the closest thing to a cure for the common cold.

Echinacea stimulates the overall activity of the cells responsible for fighting all kinds of infection. Unlike antibiotics, which directly attack bacteria, echinacea makes our own immune cells more efficient at attacking bacteria, viruses and abnormal cells, including cancer cells. It increases the number and activity of immune system cells including anti-tumor cells, promotes T-cell activation, stimulates new tissue growth for wound healing and reduces inflammation in arthritis and inflammatory skin conditions.

The most consistently proven effect of echinacea is in stimulating phagocytosis (the consumption of invading organisms by white blood cells and lymphocytes). Extracts of echinacea can increase phagocytosis by 20-40%.

Echinacea also stimulates the production of interferon as well as other important products of the immune system, including “Tumor Necrosis Factor”, which is important to the body’s response against cancer.

Echinacea also inhibits an enzyme (hyaluronidase) secreted by bacteria to help them gain access to healthy cells. Research in the early 1950’s showed that echinacea could completely counteract the effect of this enzyme, helping to prevent infection when used to treat wounds.

Although echinacea is usually used internally for the treatment of viruses and bacteria, it is now being used more and more for the treatment of external wounds. It also kills yeast and slows or stops the growth of bacteria and helps to stimulate the growth of new tissue. It combats inflammation too, further supporting its use in the treatment of wounds

One study shows E. purpurea has antidepressant properties in white rats as it increased the stimulating action of L-DOPA. Echinacea is believed by many people to stimulate the immune system.

Known Hazards : Possible suppression of immunity with habitual use. High doses over 1000 mg may cause dizziness. Use of herb for 10-14 days recommended followed by a short break.

Cercis canadensis

Botanical Name :Cercis canadensis
Family: Fabaceae
Genus: Cercis
Species: C. canadensis
Kingdom: Plantae
Order: Fabales

Common Name : Redbud or Eastern redbud

Habitat : Cercis canadensis is native to eastern North America from Southern Ontario, Canada south to northern Florida.

Description:
Cercis canadensis typically grows to 6–9 m (20–30 ft) tall with a 8–10 m (26–33 ft) spread. It generally has a short, often twisted trunk and spreading branches. A 10-year-old tree will generally be around 5 m (16 ft) tall. The bark is dark in color, smooth, later scaly with ridges somewhat apparent, sometimes with maroon patches. The twigs are slender and zigzag, nearly black in color, spotted with lighter lenticels. The winter buds are tiny, rounded and dark red to chestnut in color. The leaves are alternate, simple, heart shaped with an entire margin, 7–12 cm (3-5 inches) long and wide, thin and papery, and may be slightly hairy below.

CLICK & SEE THE PICTURES OF THE PLANT

The flowers are showy, light to dark magenta pink in color, 1.5 cm (½ inch) long, appearing in clusters from Spring to early Summer, on bare stems before the leaves, sometimes on the trunk itself. The flowers are pollinated by long-tongued bees such as blueberry bees and carpenter bees. Short-tongued bees apparently cannot reach the nectaries. The fruit are flattened, dry, brown, pea-like pods, 5–10 cm (2-4 inches) long that contain flat, elliptical, brown seeds 6 mm (¼ inch) long, maturing in August to October.

In some parts of southern Appalachia, green twigs from the eastern redbud are used as seasoning for wild game such as venison and opossum. Because of this, in these mountain areas the eastern redbud is sometimes known as the spicewood tree.

In the wild, eastern redbud is a frequent native understory tree in mixed forests and hedgerows. It is also much planted as a landscape ornamental plant. The leaves are eaten by the caterpillars of some Lepidoptera, for example the Io moth (Automeris io).

A small tree with a sturdy upright trunk which divides into stout branches that usually spread to form a broad flat head. Found on rich bottom lands throughout the Mississippi River valley; will grow in the shade and often becomes a dense undergrowth in the forest. Very abundant in Arkansas, Oklahoma, and eastern Texas. Hardy far north; grows rapidly; is a satisfactory ornamental tree. Many trees are sterile and produce no fruit. It is also known as the Judas tree.

This tree is difficult to grow as far west as western Kansas and Colorado, as there is not sufficient water. Its far northern range of growth is southern New England. It grows well in New York State, New Jersey and southward.

Two and a half to three inches long, rose color, full grown by midsummer, falls in early winter. Seeds ten to twelve, chestnut brown, one-fourth of an inch long -can be made to germinate by first dipping in boiled (99C) water (very hot) for a minute and then sowing in a pot (do not boil the seeds); cotyledons oval, flat

Cultivation;
C. canadensis is grown in parks and gardens, with several cultivars being available. The cultivar ‘Forest Pansy’, with purple leaves, has gained the Royal Horticultural Society‘s Award of Garden Merit.

Edible Uses:
Native Americans consumed redbud flowers raw or boiled, and ate roasted seeds. Analysis of nutritional components in edible parts of eastern redbud reported that:

*The flower extract contains anthocyanins,

*Green developing seeds contained proanthocyanides, and

*Linolenic, alpha-linolenic, oleic and palmitic acids to be present in seeds

Medicinal Uses:
Cercis canadensis inner bark and root can be made into a tea or decoction. This was used by different Native American Indian tribes to clear lung congestion, for whooping cough, to prevent nausea and vomiting, and to break fevers. It has also been used for diarrhea, dysentery, and leukemia.

Pulsatilla vulgaris

[amazon_link asins=’B00EVSVTDO,B008GO65RY,B004HITBS8,B008GO60II,B008GO5TPS,B004HIX300,B00RUDD2MS,B004HITBTM,B01N4DG01D’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’f9d3e526-3208-11e7-82ac-f9ece34f637a’]

Botanical Name : Pulsatilla vulgaris
Family:Ranunculaceae
Genus:Pulsatilla
Species:P. vulgaris
Kingdom:Plantae
Division:Magnoliophyta
Class:Magnoliopsida
Order:Ranunculales

Synonyms : Anemone pulsatilla

Common Name :Pasque flower, Pasqueflower, Common pasque flower, Dane’s blood,European pasqueflower

Habitat:Pulsatilla vulgaris native to Europe.It is found locally on calcareous grassland.It grows in sparsely wooded pine forests or meadows, often on a sunny sloping side with calcium-rich soil. A large colony occurs on publicly accessible land in the Cotswolds, at the Gloucestershire Wildlife Trust‘s Pasqueflower reserve.

Description:
Pulsatilla vulgaris is an herbaceous perennial plant. It develops upright rhizomes, which function as food-storage organs. Its leaves and stems are long, soft, silver-grey and hairy. It grows to 15–30 cm high and when it is fruit-bearing up to 40 cm. The roots go deep into the soil (to 1 m). The finely-dissected leaves are arranged in a rosette and appear with the bell-shaped flower in early spring. The purple flowers are followed by distinctive silky seed-heads which can persist on the plant for many months. The flower is ‘cloaked in myth’; one legend has it that Pasque flowers sprang up in places that had been soaked by the blood of Romans or Danes because they often appear on old barrows and boundary banks.

This plant has gained the Royal Horticultural Society‘s Award of Garden Merit.
Different varities of Pulsatilla vulgaris are available, while the main variety of Pulsatilla vulgaris has purplish flowers; variants include red (Rubra) and white (Alba) forms (see images).

Cultivation:
Requires a well-drained humus rich gritty soil in a sunny position. Lime tolerant. Prefers lime. Grows best in a well-drained chalky soil in a dry warm situation. Established plants are fairly drought tolerant. A very hardy plant, tolerating temperatures down to about -20°c. A very ornamental plant[1], there are many named varieties. The plant has become rare in its natural environment, due partly to over-collecting and partly to habitat loss. Large plants transplant badly. A greedy plant, inhibiting the growth of nearby plants, especially legumes.

Propagation :
Seed – best sown as soon as it is ripe in early summer in a cold frame. The seed usually germinates in about 2 – 3 weeks. Sow stored seed in late winter in a cold frame. Germination takes about 1 – 6 months at 15°c. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in the spring. Root cuttings, 4cm long taken in early winter, potted up in a mixture of peat and sand. They can also be taken in July/August, planted vertically in pots in a greenhouse or frame. Some care is needed since the plant resents root disturbance.

Medicinal Uses:
In Traditional Chinese Medicine, pulsatilla is used as an anti-inflammatory and is considered specific for amoebic and bacterial dysentery. Externally, it is used as a douche for trichomonas.
Western herbalists and homeopaths, on the other hand, use minute doses of pulsatilla as an important remedy for premenstrual syndrome. Curiously, mainly fair and blue-eyed women are responsive to this remedy. It is generally used as an emmenagogue and to increase blood and energy circulation for both men and women. It strengthens sexual sensitivity while lessening the tendency towards morbid preoccupation. It is a good remedy to consider for disorders of the reproductive organs and the prostate, associated with nervous and emotional problems. Characteristically, the symptoms treated are nervousness, restlessness and an active imagination or fear of impending danger or disease. For menstrual irregularity or delayed menstruation, it is used to treat simple suppression due to atropy or shock. It is also good for some cases of heart disease, again with strong mental symptoms.

Pulsatilla is used for various inflammatory conditions, but especially if accompanied by nervousness, despondency, sadness, unnatural fear, weepiness and depression. It is used also for headache, insomnia, neuralgia in the anemic, thick tongue coating with a greasy taste, stomach disorders from over-indulgence in fats and pastries, various alternating and shifting signs such as diarrhea/constipation, amenorrhea and dysmenorrhea, pain from exposure to wind, toothache and styes.
In France, it has traditionally been used for treating coughs and as a sedative for sleep difficulties. Pulsatilla is also used to treat eye problems such as cataracts.

Pasque flower is considered by herbalists to be of highly valuable modern curative use as a herbal simple. The plant contains the glycoside ranunculin, this is converted to anemonine when the plant is dried and is the medicinally active principle in the plant. The whole plant is alterative, antispasmodic, diaphoretic, diuretic, emmenagogue, expectorant, nervine and sedative. It is taken internally in the treatment of pre-menstrual syndrome, inflammations of the reproductive organs, tension headaches, neuralgia, insomnia, hyperactivity, bacterial skin infections, septicaemia, spasmodic coughs in asthma, whooping cough and bronchitis. Externally, it is used to treat eye conditions such as diseases of the retina, senile cataract and glaucoma. This remedy should be used with caution, excessive doses cause diarrhoea and vomiting. It should not be prescribed to patients with colds. See also the notes below on toxicity. The plant is harvested soon after flowering, it is more poisonous when fresh and so should be carefully preserved by drying. It should not be stored for longer than 12 months before being used. In homeopathy, the plant is considered to be specific in the treatment of measles. It is also used for treating nettle rash, toothache, earache and bilious indigestion.
Other Uses : ….Dye......A green dye is obtained from the flowers. Plants can be grown to form a ground cover, they are best spaced about 30cm apart each way.

Known Hazards : The plant is slightly toxic, the toxins are dissipated by heat or by drying the plant. Repeated handling of the plant can cause skin irritation in some people.

Pontederia cordata

[amazon_link asins=’B01N1SLVG6,B015OUGFZO,B01BJ47TNQ,B00HMEBUNS,B06Y2QRNGH,B00L9F7986,B015OUGH48,B000H4MYGW,B00ZAV8A1A’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ca0c27af-320c-11e7-874a-4b2992445ada’]

Botanical Name ; Pontederia cordata
Family: Pontederiaceae
Genus: Pontederia
Species: P. cordata
Kingdom: Plantae
Order: Commelinales

Common Name ;Pickerelweed (USA) or Pickerel weed (UK)

Habitat ;Pontederia cordata is native to Eastern N. America – Nova Scotia to Florida andTexas. A garden escape occ naturalized in Britain.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires wet soil and can grow in water.

Description:
Pontederia cordata is a perennial herb growing to 0.75m by 0.45m.
It is hardy to zone 3. It is in flower from July to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees.
CLICK & SEE THE PICTURES
The species grows as an emergent plant, that is, in flooded conditions, so the plant is generally dependent upon aerenchyma in the stem to carry oxygen into the roots. Its metabolism, is, however, also tolerant of low soil oxygen. It is often found in areas where water levels fluctuate naturally, with spring flooding and later summer emergence. Apart from flooding, the species is also influenced by soil fertility, tending to grow in the more fertile bays of large lakes, for example. Like many aquatic plants, it is negatively affected by salinity and grazing. It is also negatively affected by competition from other wetland plants. Like many wetland plants, it can survive infavorable conditions as buried seeds in the soil.

The plant flowers in late summer. The purple flowers have yellow markings which may assist in attracting bees for pollination.One bee species known to pollinate the flowers is Dufourea (Halictoides) novaeangliae. Once the plant begins to produce seeds, the stem supporting the infloresence bends to submerse the fruits and seeds. Seeds are dormant at the time of dispersal and will not germinate without stratification for 6-8 weeks.

The flowers of the species are tristylous, meaning the styles of individual plants occur in three different morphs, with most populations containing all three. Leaf shape, which varies considerably across populations, within populations, and even within individuals, has been the source for many taxonomic synonyms. Like many wetland and aquatic plants, the species can reproduce asexually by means of branching rhizomes, and hence can form large clonal stands.

Cultivation;
A water or bog garden plant, it requires a rich soil[56] and prefers growing in water 15 – 30 cm deep. Plants are hardy to about -25°c. A very ornamental plant, it forms spreading patches by means of a thick creeping rhizome. There is a species of bee (Dufourea novae-angliae) which visits this plant for nectar and pollen and does not visit any other species of plant. The reproductive biology of Pontederia cordata has been well studied. It is a tristylous species, and most populations contain all three forms. At least some degree of self-incompatibility exists, being strongest with the short-style forms and weakest with the midstyle forms.

Propagation:
Seed – best sown as soon as it is ripe in pots standing in 2cm of water in a cold frame. Cover the seed lightly with silver sand. Submerse in 3cm depth of water after the seedlings emerge. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in water in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division is best in April but it can be done at almost any time of the year. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer. Lateral shoots.

Edible Uses :
Edible Parts: Leaves; Seed.
Edible Uses:

Seed – raw, cooked like rice or dried and ground into a powder. A very acceptable nutty flavour and texture when raw, they are said to be excellent if the seed is lightly roasted in an oven. Young leafstalks – raw or cooked. The whole plant is edible cooked or raw. It can be added to salads, cooked like spinach or added to soups.

Medicinal Uses:
An infusion of the plant has been used as a contraceptive.
