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.

Cultivation details

Landscape Uses:Border, Foundation. Prefers a light moderately fertile and retentive soil with good drainage, though it tolerates poor dry soils[200] and grows well on chalk[11]. Requires a sunny position[11, 200]. Plants are not fully hardy in Britain, especially if treated as shrubs, but if treated as herbaceous perennials they succeed outdoors in areas where winter temperatures do not fall below about -10 to -15°c[200]. When the woody stems survive the winter it is best to prune them hard in the spring in order to obtain better flowering[11]. Plants flower best on the current years growth[200]. Most, if not all the plants in cultivation in Britain, derive from an original two plants raised from seed in 1908[11]. Plants in this genus are notably resistant to honey fungus[200]. Members of this genus are rarely if ever troubled by browsing deer[233]. Special Features: Blooms are very showy.

Propagation

Seed - we have no details for this species but suggest sowing the seed in a greenhouse in the spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division of rooted suckers in the spring[200]. Layering in the spring. Plants often self-layer[200]. Cuttings of half-ripe wood in a closed frame[200]. Plants should be overwintered in a frost-free frame or greenhouse for their first winter[200].
