Astragalus floridus

Botanical Name : Astragalus floridus
Family: Fabaceae
Subfamily: Faboideae
Tribe: Galegeae
Subtribe: Astragalinae
Genus: Astragalus
Kingdom: Plantae
Order: Fabales

Common Name : Duo Hua Huang Qi

Habitat : Astragalus floridus is native to East AsiaHimalayas. It grows in the forests and alpine meadows at elevations of 3800-4400 metres in the Himalayan regions of Sikkim and western China.

Description:
Astragalus floridus is a perennial herb growing to 0.3 m (1ft). It is in flower from Jul to August, and the seeds ripen from Aug to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, lepidoptera.It can fix Nitrogen.
Suitable for: light (sandy) and medium (loamy) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry soil.   CLICK  &  SEE THE PICTURES

Cultivation:
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. Whilst it is likely to tolerate low temperatures it may not be so happy with a wet winter. The following notes are based on the general needs of the genus. Requires a dry well-drained soil in a sunny position. Succeeds in poor soils. Plants are intolerant of root disturbance and are best planted in their final positions whilst still small. This plant is a sub-shrub and although it produces woody stems these tend to die back almost to the base each winter. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. Many members of this genus can be difficult to grow, this may be due partly to a lack of their specific bacterial associations in the soil.
Propagation:
Seed – best sown as soon as it is ripe in a cold frame. A period of cold stratification may help stored seed to germinate. Stored seed, and perhaps also fresh seed, should be pre-soaked for 24 hours in hot water before sowing – but make sure that you do not cook the seed. Any seed that does not swell should be carefully pricked with a needle, taking care not to damage the embryo, and re-soaked for a further 24 hours. Germination can be slow and erratic but is usually within 4 – 9 weeks or more at 13°c if the seed is treated or sown fresh. As soon as it is large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts.
Medicinal Uses:
The entire plant is used in Tibetan medicine, it is said to have a sweet taste and a heating potency. Antihydrotic, diuretic, emmenagogue and tonic, it is used in the treatment of body weakness from prolonged illness, renal inflammation from lack of exercise, lack of appetite, excessive perspiration (especially when asleep), diabetes, boils/sores, diarrhoea, irregular menses and vaginal/seminal discharge.
Known Hazards: Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element.

Astragalus canadensis

Botanical Name: Astragalus canadensis
Family: Fabaceae
Genus: Astragalus
Species: A. canadensis
Kingdom: Plantae
Order: Fabales

Synonyms: Astragalus carolinianus. L.
Common Names : Canadian Milkvetch, Shorttooth Canadian milkvetch, Morton’s Canadian milkvetch
Habitat: Astragalus canadensis is native to Central and eastern N. America – Quebec to Saskatchewan, New York, Louisiana, Nebraska and Utah. IIt grows on shores and rich thickets. Rocky and sandy thickets in Texas.

Description:
Astragalus canadensis is a perennial herb growing to 1 m (3ft 3in). It sends out several thin, erect, green stems, bearing leaves that are actually made up of pairs of leaflets, each leaflet up to 3 centimeters in length. It has inflorescences of tubular, greenish-white flowers which yield beanlike fruits within pods that rattle when dry.

Pagoda-like towers of creamy yellow flowers rise above the dark green leaves in mid-summer, followed by scepters of bead-like seed pods in August. This striking member of the Pea family is an important food for birds, as it retains its seed late into the fall and early winter.

The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, lepidoptera.It can fix Nitrogen.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry soil.

Cultivation:
Requires a dry well-drained soil in a sunny position. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. Plants are intolerant of root disturbance and are best planted in their final positions whilst still small. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.

Edible Uses:

Root – raw or boiled. They were often used in a broth. The roots are gathered in spring or autumn. Some caution is advised, if the root is bitter it could be due to the presence of toxic alkaloids.
Medicinal Uses:
The root is analgesic and antihaemorrhagic. It can be chewed or used as a tea to treat chest and back pains, coughs and the spitting up of blood. A decoction of the root is used as a febrifuge for children. A poultice made from the chewed root has been used to treat cuts

Known Hazards: Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage.

Amaranthus hypochondriacus

Botanical Name : Amaranthus hypochondriacus
Family: Amaranthaceae
Genus: Amaranthus
Species: A. hypochondriacus
Kingdom: Plantae
Order: Caryophyllales

Synonyms: Love-Lies-Bleeding. Red Cockscomb. Velvet Flower.

Common Names :   Amaranths,Prince-of-Wales feather or prince’s feather (it is called quelite, blero and quintonil in Spanish.)

Habitat: The Amaranths are met with most abundantly in the tropics, especially in tropical America, but are not plentiful in cold countries.It grows as weed of wasteland and agricultural land.

Many species are widely distributed as pernicious weeds. Their economic importance is slight, their properties chiefly proteid nutrient. Many abound in mucilage and sugar and many species are used as pot-herbs, resembling those of Chenopodiaceae. Many, also, are excellent fodder-plants, though not cultivated.

Description;
Amaranthus hypochondriacus is a annual herb, growing to 1.2 m (4ft) by 0.5 m (1ft 8in).
It is frost tender. It is in leaf 10-Apr It is in flower from Jul to August, and the seeds ripen from Aug to September. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind, self.The plant is self-fertile.  CLICK & SEE THE PICTURES

Cultivation:                                            
Prefers a well-drained fertile soil in a sunny position. Requires a hot sheltered position if it is to do well. Tolerates a pH in the range 5.2 to 7.5. Plants should not be given inorganic fertilizers, see notes above on toxicity. Often cultivated, especially in tropical areas, for its edible leaves and seeds, there are many named varieties. This is the most robust and highest yielding of the grain amaranths, though it is late maturing and therefore less suitable for northern areas. Most if not all members of this genus photosynthesize by a more efficient method than most plants. Called the ‘C4 carbon-fixation pathway’, this process is particularly efficient at high temperatures, in bright sunlight and under dry conditions.

Propagation: 
Seed – sow late spring in situ. An earlier sowing can be made in a greenhouse and the plants put out after the last expected frosts. Germination is usually rapid and good if the soil is warm. A drop in temperature overnight aids germination. Cuttings of growing plants root easily

Edible Uses:    
Young leaves are eaten cooked as a spinach. Rich in vitamins and minerals, they have a mild flavour.

Seed are eaten raw or cooked. They can be used as a cereal substitute. They can also be popped in much the same way as popcorn. The seed can be soaked for 12 hours in warm water and then allowed to sprout for about 11 days. They can then be added to salads. Very small but the seed is easy to harvest and very nutritious. The seed can be cooked whole, and becomes very gelatinous like this, but it is rather difficult to crush all of the small seeds in the mouth and thus some of the seed will pass right through the digestive system without being assimilated. A red pigment obtained from the plant is used as a food colouring.

 

Medicinal Uses:
The whole plant contains tannin and is astringent. It is used internally in the treatment of diarrhoea and excessive menstruation. It can be used as a gargle to soothe inflammation of the pharynx and to hasten the healing of ulcerated mouths, whilst it can also be applied externally to treat vaginal discharges, nosebleeds and wounds. The plant can be used fresh or it can also be harvested when coming into flower and dried for later use.

Other Uses
Dye…..Yellow and green dyes can be obtained from the whole plant. A red dye obtained from the plant (the report does not specify which part of the plant) is used as a colouring in foods and medicines.

Known Hazards:  No members of this genus are known to be poisonous, but when grown on nitrogen-rich soils they are known to concentrate nitrates in the leaves. This is especially noticeable on land where chemical fertilizers are used. Nitrates are implicated in stomach cancers, blue babies and some other health problems. It is inadvisable, therefore, to eat this plant if it is grown inorganically.
