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

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of the country. We do not know the plants cultivation needs.

Link: Wild Food Foragers of America Newsletter features one edible weed per month, how to harvest, store and prepare. Hawksbeard is a wonderful spring salad green, a good detox tea, and source of chlorophyll in the diet. Use as a food like dandelion, but is more prolific and easier to harvest.
