Safety & Hazards
The leaves of the plants have stinging hairs, causing irritation to the skin[1, 2]. This action is neutralized by heat so the cooked leaves are perfectly safe and nutritious[2]. However, only young leaves should be used because older leaves develop gritty particles called cystoliths which act as an irritant to the kidneys[3].
Cultivation Details
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 most parts of the country. It is closely related to U. dioica, and may be no more than an eastern variant of that species[4]. The following notes are based on the general needs of the genus. Prefers a nitrogen-rich soil[2]. The best fibre is produced when plants are grown on deep fertile soils[2]. A dioecious species - both male and female forms must be grown if fruit and seed are required.
Propagation
Seed - sow spring in a cold frame, only just covering the seed. Prick out the seedlings into individual pots when they are large enough to handle, and plant them out in the summer. Division succeeds at almost any time in the growing season. Very easy, plant them straight out into their permanent positions.
