We rely on donations from our users to keep maintaining and extending our free-to-use database of over 8000 edible and useful plants. Currently we are also investing time and effort in preparing two new books on plants suitable for food forests in different warmer climate conditions, to complement the one we published in 2021 on temperate food forests, which has been very well received. Please give what you can to help us complete this work. More >>>

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.

Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first winter in the greenhouse. Plant them out in late spring or early summer after the last expected frosts. Division as the plant comes into growth in the spring[200]. Suckers. Best removed in the autumn and grown on in the greenhouse for the first winter.

Aspidistra is now placed in the Ruscaceae not Convallariaceae. Aspidistra lurida Ker-Gawl is not a synonym of A. elatior, it is a distict species. Aspidistra lurida Hort. is a synonym of A. elatior. The native range of A. elatior is Japan only; specifically the island groups mentioned above. I agree A. elatior is inedible but how can it have a rating of 0 on a scale of 1-5? 1 is inedible but 0 is really inedible? Shades of Spinal Tap! Saying that A. elatior is hardy to (USDA) zone 7 implies it tolerates an annual average minimum temperature of -17.7C to -12.3C. If this were true it would be hardy throughout the UK (including the Scottish Highlands) and its reputed survival in a Worcestershire garden for over 30 years would be completely unexceptional. In other words it is nonsense to say that it is hardy to (USDA) zone 7. It is hardy in zone 8 with protection. How can A. elatior "prefer" every known soil type? It prefers a fertile, well drained loamy soil a little on the alkaline side but will tolerate other soils. It does not "require" dry or moist soils. It prefers moist soils but is drought tolerant. It is a myth that slugs and snails pollinate A. elatior. Tiny terrestrial arthropods called collembolans are responsible. Seed would a feasible method of propagating Aspidistra elatior but it is not available comercially and plants very rarely fruit in cultivation so the information provided is irrelevant. Plants are propagated by rhizome division in the spring. The comment about "suckers" (not produced by Aspidistra) is wrong and irrelevant.
