Polygonum molle

Propagation: Seed - sow spring in a cold frame. Germination is usually free and easy. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer if they have reached sufficient size. If not, overwinter them in a cold frame and plant them out the following spring after the last expected frosts.

Division in spring or autumn. 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.

Cultivation: Succeeds in an ordinary garden soil[1] but prefers a moisture retentive not too fertile soil in sun or part shade[2]. Repays generous treatment[1]. A very fast growing plant[3].

Plants seem to be immune to the predations of rabbits[4].

Range: E. Asia - Himalayas from Uttar Pradesh to S.W. China.

Habitat: Forest, scrub and damp ground, often gregarious, 900 - 4250 metres[5][6]. Slopes, forests, grassy places and thickets in valleys at elevations of 1300 - 3500 metres[7].

Edibility: Young shoots - raw or cooked as a vegetable[3][8][9]. Pleasantly acid, they are used like rhubarb[10].

Seed - raw or cooked. It is rather small and fiddly to utilize.

Medicinal: The whole plant is astringent[11].

Usage: Plants are very fast growing and are used to reclothe and stabilize land slips[3]. They are best spaced about 1.2 metres apart each way[12].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Seed Ripens: Late Summer-Mid Fall

Flower Type: Hermaphrodite

Known Hazards: Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people._x005F

Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) - whil

Also Known As: Aconogonum molle. (D.Don.)Hara. Persicaria mollis. (D.Don.)Gross.
