It is hardy to zone 7.  The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.

Noteworthy characteristics: When crushed, the foliage smells like unsweetened peanut butter, thought it is often described as “fetid.

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 moist soil.

Cultivation :
Succeeds in a sunny position in ordinary garden soil but prefers a fertile humus-rich well-drained loam. The soil must not be allowed to dry out in the growing season. Requires a position sheltered from cold drying winds. Plants are generally hardy to about -15°c, they succeed outdoors at Kew though the branches are pithy and are apt to die back in winter. The sub-species C. trichotomum fargesii. (Dode.)Rehder. is somewhat hardier, tolerating temperatures down to about -20°c. Plants produce the occasional sucker. The leaves have a heavy unpleasant odour when crushed. Flowers are produced on the current seasons growth and are sweetly scented.

Propagation:
Seed – best sown as soon as possible in a greenhouse. Germination can be erratic but usually takes place within 20 – 60 days at 20°c. When 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 in late spring or early summer after the last expected frosts. Root cuttings, 6 – 8cm long, December in a greenhouse. High percentage. Division of suckers in the dormant season. Very easy, they can be planted out direct into their permanent positions if required.

Edible Uses:
Edible Parts: Leaves.

Young sprouts and leaves – cooked.

Medicinal Uses:
Analgesic; Antipruritic; Antirheumatic; Hypotensive; Parasiticide; Sedative.

The leaves are mildly analgesic, antipruritic, hypotensive and sedative. They are used externally in the treatment of dermatitis and internally for the treatment of hypertension, rheumatoid arthritis, joint pain, numbness and paralysis. When used in a clinical trial of 171 people, the blood pressure of 81% of the people dropped significantly – this effect was reversed when the treatment was stopped. The plant is normally used in conjunction with Bidens bipinnata. When used with the herb Siegesbeckia pubescens it is anti-inflammatory. The roots and leaves are antirheumatic and hypotensive. A decoction is used in the treatment of rheumatoid arthritis and hypertension. The pounded seed is used to kill lice.

Other Uses:

Scented Plants
Flowers: Fresh
The flowers are sweetly scented.
Leaves: Crushed
The leaves have a heavy unpleasant odour when crushed.

Codium fragile

[amazon_link asins=’B000734F7O,B012BR0ZOU,B004V309Z8,B075KMBCJR,B073GWKGQ2,B0050BJ2TO,B0776D9RTY,B00AMTW6RO’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’2739ad54-e3b0-11e7-a21a-9543738bc67d’]

Botanical Name : Codium fragile
Family: Codiaceae
Genus: Codium
Species: C. fragile
Kingdom: Plantae
Division: Chlorophyta
Class: Bryopsidophyceae
Order: Bryopsidales

Common Names :Green sea fingers, Dead man’s fingers, Felty fingers, Felt-alga, Green sponge and  Green fleece

Habitat :Codium fragile is native to the Pacific Ocean. The species inhabits the middle and lower intertidal zone as well as subtidal regions of rocky shores.

It is also found in large tide pools permanently filled with water. Therefore it is found at Race Rocks. At Race Rocks in 2001, the species occurred in only two small areas, although it was found when diving in earlier years in larger beds, shallow subtidally on the south side of Bentinck Island just across Race Passage north from Race Rocks. On the north side of the Great Race, there was one plant in a tide pool, and on the South East side, several dozen plants have occurred since the early 1980’s along the zero tide level of the small peninsula island. In 2004 it has been observed in several tidepools however its population still remains limited.

Description:
Codium fragile is a dark green alga, ranging from ten to 40 cm high and consists of repeatedly branching cylindrical segments about 0.5 to 1.0 cm in diameter, and the branches can be as thick as pencil. The segments look like dark green fingers. Its holdfast is a broad, sponge like cushion of tissue. The tips of segments are blunt and the surface is soft, so it is sometimes mistaken as a sponge. Its body consists of interwoven, filamentous cells with incomplete crosswalls forming the inner part of the branches.

A number of subspecies have been described, some of which have been introduced in various parts of the world. Although two spubspecies were widely accepted as having been introduced into Britain and Ireland, recent detailed genetic studies have shown that this is not the case.

Medicinal Uses;
In China, used to clear away heat and toxic materials, reduce tumescence and nourish dampness and driving bug. For edema, difficulty of pisses, driving lumbricoid and drink.

Chinese Woad (Isatis tinctoria or Isatis indigotica)

English: Isatis tinctoria, Brassicaceae, Woad,...
English: Isatis tinctoria, Brassicaceae, Woad, habitus Deutsch: Isatis tinctoria, Brassicaceae, Färberwaid, Deutscher Indigo, Habitus (Photo credit: Wikipedia)

Botanical Name : Isatis tinctoria /Isatis indigotica
Family: Brassicaceae/Cruciferae
Genus: Isatis
Species: I. tinctoria
Kingdom: Plantae
Order: Brassicales

Synonyms: Isatis indigotica – Fortune.

Common Name:  Chinese Woad
Other Common Names: Ban Lan Gen, Ch’Ing Tai, Dyer’s Woad, Dyer’s-woad, Tein-ching, Tien Hua, Wede, Woad

Habitat :Woad is native to the steppe and desert zones of the Caucasus, Central Asia to eastern Siberia and Western Asia (Hegi), but is now found in southeastern and some parts of Central Europe as well.Grows in  cliffs and cornfields, often on chalky soils.

Description:
Isatis indigotica is Biennial/Perennial growing to 1m by 0.45m.
It is hardy to zone 7 and is not frost tender. It is in flower from June to August, and the seeds ripen from August to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Cultivation:
An easily grown plant, it prefers a well-drained fertile soil in a sunny position, though it succeeds in ordinary garden soil. Prefers neutral to alkaline conditions. Plants deplete the soil of nutrients and cannot be grown successfully on the same site for more than two years. Plants are hardy to about -15°c. Woad is a biennial, or occasionally a short-lived perennial plant. It has a very long history as a dye plant, being used by the ancient Britons to give a blue colouring to the skin. At one time woad was widely cultivated for this blue dye obtained from its leaves but with the advent of chemical dyes it has fallen into virtual disuse. It is currently (1993) being grown commercially on a small scale in Germany as a wood preservative (An item on BBC’s Radio 4 Farming Programme). Plants self-sow freely when they are grown in a suitable position, though they tend not to thrive if grown in the same position for more than two years.

Propagation:
Seed – sow spring in situ. Fresh seed can also be sown in situ in late summer, it will take 20 months to flower but will produce more leaves

Edible Uses
Edible Parts: Leaves.

Leaves – they require long soaking in order to remove a bitterness, and even then they are still bitter[177, 179]. There is no record of the seeds being edible, but they contain 12 – 34% protein and 12 – 38% fat on a zero moisture basis[218].

Medicinal Uses:
Antibacterial; Antiviral; Astringent; Cancer.

Isatis indigotica contains indican and isatin B, both of which can be converted to indigo. Considered antibacterial, antiviral, and anti-inflammatory. Leaves and roots are effective against flu, encephalitis, measles, hepatitis, and mumps.

Woad has rather a mixed press for its medicinal virtues. One author says it is so astringent that it is not fit to be used internally – it is only used externally as a plaster applied to the region of the spleen and as an ointment for ulcers, inflammation and to staunch bleeding[4]. However, it is widely used internally in Chinese herbal medicine where high doses are often employed in order to maintain high levels of active ingredients. The leaves are antibacterial, anticancer, antiviral, astringent and febrifuge. It controls a wide range of pathogenic organisms, including viruses. It is used internally in the treatment of a wide range of disorders, including meningitis, encephalitis, mumps, influenza, erysipelas, heat rash etc. The leaves are harvested in the summer and can be used fresh or dried. They are also macerated and the blue pigment extracted. This is also used medicinally, particularly in the treatment of high fevers and convulsions in children, coughing of blood and as a detoxifier in infections such as mumps. The root is antibacterial and anticancer. It is used in the treatment of fevers, pyogenic inflammation in influenza and meningitis, macula in acute infectious diseases, erysipelas, mumps and epidemic parotitis. Its antibacterial action is effective against Bacillus subtilis, haemolytic streptococcus,, C. diphtheriae, E. coli, Bacillus typhi, B. paratyphi, Shigella dysenteriae, S. flexneri and Salmonella enteritidis. Both the leaves and the roots are used in the treatment of pneumonia. The root and the whole plant have anticancer properties whilst extracts of the plant have shown bactericidal properties.

Other Uses
Dye; Preservative.

Woad is historically famous as a dye plant, having been used as a body paint by the ancient Britons prior to the invasion of the Romans. A blue dye is obtained from the leaves by a complex process that involves fermenting the leaves and produces a foul stench. The dye is rarely used nowadays, having been replaced first by the tropical Indigofera tinctoria and more recently by synthetic substitutes. Nevertheless, it is a very good quality dye that still finds some use amongst artists etc who want to work with natural dyes. A very good quality green is obtained by mixing it with Dyer’s greenwood (Genista tinctoria). Woad is also used to improve the colour and quality of indigo, as well as to form a base for black dyes. The leaves are harvested when fully grown and 3 – 4 harvests can be made in total. Recent research in Germany has shown that (the dyestuff in?) this plant is a very good preservative for wood[Radio 4 Farming programme].

Habitat :Chinese Violet is widespread throughout the Old World Tropics, and introduced into tropical Americas and Hawaii, where it has become naturalized. Both subspecies of this plant have been introduced to Australia where A. g. micrantha is on the National Environmental Alert List and must be reported when found. The original range of the subspecies is unclear, but it is likely that A. g. gangetica was limited to Asia, and A. g. micrantha was limited to Africa

Description:
This plant is a spreading herb or groundcover, reaching 2 feet in height or up to 3 feet  if supported. The stems root easily at the nodes. The leaves are simple and opposite. The fruit is an explosive capsule which starts out green in colour, but dries to brown after opening……

Edible  Uses:
In some parts of Africa, the leaves are eaten as a vegetable.

Medicinal Uses;
Chinese Violet is  used as an herbal remedy in traditional African medicine. The leaves are used in many parts of Nigeria for the management of asthma, and scientific investigation has shown some basis for this use.

Other Uses;
Chinese Violet is used as an ornamental plant in several places.This is also an important plant for honeybees, butterflies and other insects. In southern Africa there are at least six species of butterfly that use A. g. micrantha as a larval foodplant; Junonia oenone, Junonia hierta, Junonia natalica, Junonia terea, Protogoniomorpha parhassus and Hypolimnas misippus. The vigorous growth of A. g. micrantha in tropical regions makes it a weed which can smother certain indigenous vegetation where it has been introduced.

Rhus chinensis

[amazon_link asins=’B06XQDP4KM,B01N2XZBAU,B01DE0Z9VM,B072MQSKQV,B071WTX7DM,B00BURC58C,B07218XHMH,B071WVMLWQ,B008RYLPC8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’1e74f4b6-504b-11e7-a3f4-79fbc74b90d4′]

Botanical Name : Rhus chinensis
Family: Anacardiaceae
Genus: Rhus
Species: R. chinensis
Kingdom: Plantae
Order: Sapindales

Synonyms : Rhus javanica – Thunb. non L., Rhus osbeckii – Decne., Rhus semialata – Murray.

Common Names : Chinese gall, Galla Chinensis or Wu Bei,Chinese Sumac

Habitat : Rhus chinensis is native to E. Asia – China, Japan. Grows in  lowland, hills and mountains in Japan. Also found in the Himalayas (as R. semialata) where it grows in secondary forests to 2100 metres

Description:
Rhus chinensis forms a loose, spreading small tree, reaching up to 25 feet in height . Most specimens only grow to about 12 to 15 feet tall. Theshiny, pinnately compound, five inches long leaves change to a brilliant orange, red, or yellow in the fall before dropping. The yellowish-white, summertime flowers appear in 6 to 10-inch-long and wide, terminal panicles and are quite showy. The hairy fruits which follow are orange/red and mature in October.
CLICK & SEE THE PICTURES
It is hardy to zone 8 and is frost tender. It is in flower in August, and the seeds ripen in October. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Bees. The plant is not self-fertile.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil.

Cultivation :
Succeeds in a well-drained fertile soil in full sun. A very ornamental plant, it is not fully hardy in all parts of Britain and needs a hot summer in order to fully ripen its wood, suffering winter damage to late growth if the temperature falls below about -7°c. The young growth in spring can be damaged by late frosts. The plants are also susceptible to coral spot fungus and any winter damage will exacerbate the situation. Plants have brittle branches and these can be broken off in strong winds. Many of the species in this genus are highly toxic and can also cause severe irritation to the skin of some people, whilst other species such as this one are not poisonous. It is relatively simple to distinguish which is which, the poisonous species have axillary panicles and smooth fruits whilst non-poisonous species have compound terminal panicles and fruits covered with acid crimson hairs. The toxic species are sometimes separated into their own genus, Toxicodendron, by some botanists. Plants in this genus are notably resistant to honey fungus. Dioecious. Male and female plants must be grown if seed is required.

Propagation:
Seed – best sown in a cold frame as soon as it is ripe. Pre-soak the seed for 24 hours in hot water (starting at a temperature of 80 – 90c and allowing it to cool) prior to sowing in order to leach out any germination inhibitors. This soak water can be drunk and has a delicious lemon-flavour. The stored seed also needs hot water treatment and can be sown in early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on 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. Cuttings of half-ripe wood, 10cm with a heel, July/August in a frame. Root cuttings 4cm long taken in December and potted up vertically in a greenhouse. Good percentage. Suckers in late autumn to winter

Edible Uses:
Edible Parts: Fruit.

Edible Uses: Curdling agent; Salt.

Fruit – cooked. An acid flavour. It is also used medicinally. The fruit can be used as a salt or a rennet substitute.

Medicinal Uses :

Anthelmintic; Antiphlogistic; Antiseptic; Astringent; Cholagogue; Depurative; Haemostatic.

The leaves and the roots are depurative. They stimulate blood circulation. A decoction is used in the treatment of haemoptysis, inflammations, laryngitis, snakebite, stomach-ache and traumatic fractures. The stem bark is astringent and anthelmintic. The fruit is used in the treatment of colic. The seed is used in the treatment of coughs, dysentery, fever, jaundice, malaria and rheumatism. The root bark is cholagogue. Galls on the plant are rich in tannin. They are used internally for their astringent and styptic properties to treat conditions such as diarrhoea and haemorrhage. They are a frequent ingredient in polyherbal prescriptions for diabetes mellitus. An excrescence produced on the leaf by an insect Melaphis chinensis or M. paitan (this report probably refers to the galls produced by the plant in response to the insect) is antiseptic, astringent and haemostatic. It s used in the treatment of persistent cough with blood, chronic diarrhoea, spontaneous sweating, night sweats, bloody stool, urorrhoea and bloody sputum. It is used applied externally to burns, bleeding due to traumatic injuries, haemorrhoids and ulcers in the mouth. Some caution is advised in the use of the leaves and stems of this plant, see the notes above on toxicity.

Other Uses:
Dye; Ink; Mordant; Oil; Tannin; Wax.

The leaves are rich in tannin. They can be collected as they fall in the autumn and used as a brown dye or as a mordant. A blue dye is obtained from insect galls on the plant, it can also be used as an ink. The galls are formed as a result of damage by the greenfly, Aphis chinensis. The galls contain up to 77% tannin. The reports do not say if the galls are harvested before or after the insect has left the gall. An oil is extracted from the seeds. It attains a tallow-like consistency on standing and is used to make candles. These burn brilliantly, though they emit a pungent smoke. The wood is soft and is not used.
