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:Container, Ground cover, Rock garden, Specimen. Easily grown in a sandy soil in a warm dry position in sun or light shade[1, 200]. Grows well in a dry shady corner[260]. Plants are not very cold-hardy in Britain, tolerating temperatures down to about -3°c[260]. Given a suitable position, it should succeed outdoors at least in the mildest parts of the country[K]. It should be possible to grow it even in the colder areas by digging up the bulbs in the autumn after the top growth has been cut down by frosts, storing them in a cool but frost-free place and replanting them in mid to late spring[K]. There are two main forms of this plant, ssp triangularis has smaller, green leaves and is, in our experience, slightly the hardier of the two. Ssp papilionacea has larger, dark purple leaves and is considered the more ornamental[K]. Special Features:Attractive foliage.

Propagation
Seed - best sown as soon as it is ripe in a cold frame. The seed from one subspecies does not always come true - on at least one occasion we have hade the purple-leaved form grow from seed of the green leaved form that had definitely not been cross-pollinated[K]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a greenhouse for their first winter. Plant them out in late spring or early summer. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
