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

A herbaceous perennial with showy flowers. Prefers full sun to light shade, moist soil containing loam or silt. There should be sufficient organic material in the soil to retain moisture. Spread aggressively in moist open ground, otherwise it presents few problems. In some areas of the U.S., the species is considered to be a spreading weed. Drought tolerance is poor. Plants will grow in wet areas. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [1-2].
