Now available: PLANTS FOR YOUR FOOD FOREST: 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

Best grown in moist, fertile, medium to wet soils in part shade to full shade. Soils should not be allowed to dry out. In full sun and hot sites foliage tends to bleach to an unattractive yellow. Tolerates: Deer, Heavy Shade, Erosion, Wet Soil. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is clumping, giving the plant a 'clumping' habit. The predictable growth behaviour makes it easier to maintain without having to apply containment methods[2-1].
