Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Habitats

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].

A decoction of the plant is used in the treatment of fevers[257]. The root is diuretic[257]. An infusion of the crushed roots has been used to facilitate childbirth[257].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

A fibre obtained from the stem is used for making nets, cordage etc[4, 46, 61, 159, 257]. It is up to 50 times stronger than cotton[123].

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. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a runner spreading indefinitely by rhizomes or stolons [1-2].

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.
