Physical Characteristics
An evergreen Perennial growing to 0.6m by 0.3m.
It is hardy to zone 5 and is not frost tender. It is in leaf all year, in flower from May to August, and the seeds ripen from July to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees.
The plant is self-fertile.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil.
The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil.
It cannot grow in the shade.
It requires moist soil.
The plant can tolerate maritime exposure.
Young leaves and shoots - raw or cooked[2, 5, 9, 14, 21]. They are best used before the plant comes into flower[9]. Eaten in salads, used as a garnish or added to soups, cooling drinks and claret cups[183]. Young seedlings are boiled and eaten[183]. A bit fiddly to harvest and the leaves sometimes become bitter in hot dry summers, but they are usually fairly mild tasting in the winter and some people detect a cucumber flavour to them[K]. In the acid soil of our Cornish trial grounds, the leaves have a distinctly bitter flavour, though when the same plants were grown on a chalky soil they had a much milder flavour[K]. The leaves contain about 5.65% protein, 1.2% fat, 11% carbohydrate, 1.7% ash, 74.5% water[179].
A herb tea is made from the dried leaves[21, 183].
Composition

Always seek advice from a professional before using a plant medicinally.
Both the root and the leaves are astringent, diaphoretic and styptic, though the root is most active[4]. The plant is an effective wound herb, quickly staunching any bleeding[244]. An infusion is used in the treatment of gout and rheumatism[244]. The leaves can be used fresh, or are harvested in July and dried (the plant should be prevented from flowering)[4]. The root is harvested in the autumn and dried[4].
An infusion of the leaves is used as a soothing treatment for sunburn or skin troubles such as eczema[201].
Plants have extensive root systems and are used for erosion control, they are also used to reclaim landfills and mined-out terrain[160].
Cultivation details
Prefers a light dry calcareous soil[1, 37, 200] but succeeds in most good soils[1, 37]. Plants also succeed in poor soils[4]. One report says that it grows well in marshy soil[24] but this is possibly a mistake[K]. Dislikes shade[14].
Occasionally cultivated in the herb garden, this is an evergreen herbaceous plant and it supplies fresh edible leaves all the year round, even in quite severe winters[K]. When grown as a salad, the plant should be prevented from flowering[4].
Grows well in the spring meadow[24]. Makes a good edging plant in the border[200].
Plants often self-sow, sometimes to the point of nuisance[K].
Propagation
Seed - sow March/April or September/October in a cold frame. Germinates in 3 weeks. Prick out the seedlings when they are large enough to handle into individual pots. Plant them out in the spring or early summer.
The seed can also be sown in situ in spring or autumn if you have sufficient seed.
Division in spring.

Weeds as a future source for human consumption

We reciently recieved this article on the use of various weeds
in south america. We though that you might enjoy it.
Abstract
Weeds may constitute an additional food source for humans. Up to 66% of weed species are edible and
abound in urban and agricultural environments. A total of 43 species were sampled in tropical areas in
Coatepec Mexico (e.g. roadsides, urban vacant lots, streets, sugar cane and coffee plantations). A similar
survey performed in a temperate area in Bariloche Argentina with 32 species sampled. At a greater
geographic scale, a comparison between Mexican and Argentine weeds shows that, proportionately, the
food parts vary a little between regions. In general, the uses go from leaves, seeds, roots, fruits, and
flowers.
