Edible uses

Young leaves - cooked[3][5][1][2]. Very nutritious, they are used like spinach. Some caution should be observed when harvesting this plant since the raw leaves have stinging hairs. It is perfectly safe to eat the leaves when they are cooked, however, since heat completely destroys the sting[K].

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - sow 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. Division in spring. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

We have very little information on this plant and do not know how hardy it is, but it is succeeding outdoors at Kew on the sheltered sunny side of a woodland garden[K]. It should succeed in most soils in semi-shade.
