Polygonum orientale (common name: prince's feather)

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.

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].

Plants are not very hardy in Britain but can be grown as a half-hardy annual[1].

Habitat: Roadsides, near houses and wastelands, also commonly cultivated in gardens, from sea level to 3000 metres[4].
