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 in full sun[1, 187]. Prefers a deep rather rich sandy loam[1]. Best grown in a crevice in a rock garden or on a wall[1, 187]. Tolerates hot dry conditions and also drought once it is established, but disliking winter wet[190]. Plants also dislike wet summers[200]. Hardy to about -15°c[187]. There is some confusion over this species. It is given as a part of O. frutescens in some reports but [200] gives it specific status. A very ornamental plant[1].
