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
Requires a well-drained soil and a sunny sheltered position[182, 200]. Succeeds in poor and in dry soils, growing well on sunny banks[182]. Tolerates atmospheric pollution and salt-laden winds[200]. Plants are hardy to about -20°c[200]. Flowers are produced on the current year's growth[200]. Plants in this genus are notably resistant to honey fungus[200]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].

Propagation
Seed - pre-soak for 24 hours in hot water and sow late winter in a greenhouse[113]. Scarification can help speed up the germination process[164]. Germination can be slow and erratic[200], though treated seed usually germinates in 1 - 3 months at 20°c[164]. As soon as 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 in late spring or early summer, after the last expected frosts. This species is a hybrid and so is unlikely to breed true from seed. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame[78]. Cuttings are not very long-lived[78].
