Edible Uses
Edible Parts: Flowers Leaves
Edible Uses: Tea
Young leaves and flower buds - raw or cooked[105]. A mild flavour, though the leaves soon become quite tough[K]. The leaves make a very acceptable addition to salads[K]. When added to soup they thicken it in much the same way as okra[85, 159]. A tea can be made from the leaves[85].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses
A good ground cover plant, fast spreading but slow to thicken up and may need weeding for the first year or so[197]. Plants should be spaced about 30cm apart each way[208]. A dynamic accumulator gathering minerals or nutrients from the soil and storing them in a more bioavailable form - used as fertilizer or to improve mulch.

Landscape Uses:Border,Ground cover, Rock garden, Woodland garden. Cool moist well-drained humus-rich soil in partial or dappled shade and protection from scorching winds. Succeeds in dense shade[197]. Tolerates sandstone and limestone soils but becomes chlorotic if the pH is too high. Prefers a pH between 6 and 6.5. Hardy to about -25°c[187]. There are some named varieties selected for their ornamental value[200]. All members of this genus have more or less edible leaves and flower buds, though those species with yellow flowers can cause diarrhoea if eaten in large quantities[62, 85, 159]. Special Features:Attractive foliage, North American native, Naturalizing, Attracts butterflies, Suitable for cut flowers. 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.

Propagation
Seed - best sown in the autumn in a cold frame. Sow stored seed in early spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Division in the autumn or just after flowering. Larger divisions can be planted out direct into their permanent positions, though we have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring.
