Edible Uses
Edible Parts: Leaves.
Edible Uses:
Young leaves - cooked[105]. Very nutritious and with a delicious flavour, they are used like spinach[159]. 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].

Cultivation details
We have very little information on this plant and do not know how hardy it is, but it succeeds outdoors at Kew and Cambridge Botanical Gardens as well as our trial grounds in Cornwall[K]. It should succeed in most soils in sun or semi-shade.
Propagation
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.
