Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Edible Parts: Leaves  Root
Edible Uses:

Root - cooked.[46, 61, 105] The root is fibrous according to one report[100] whilst another says that the swollen root has radical root fibres[42]. The plant is eaten as a vegetable, records of 'edible bulbs' seem to be erroneous[177].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Diuretic  Skin

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

Succeeds in ordinary garden soil, tolerating partial shade[200]. Requires a well-drained soil. Prefers a deep rich sandy loamy soil[1, 42]. Prefers a sunny position in a soil that is not too rich[200]. Grows well on hot dry banks[42]. This species is often a short-lived perennial[270], though it is not very hardy in Britain. This has contributed to the mistaken belief that it is an annual. A covering of bracken overwinter is usually ample protection in most districts[42]. Asphodelus fistulosus has become a noxious weed in California and in other places with Mediterranean climates worldwide[270]. The flowers are sweetly scented[245]. Plants seem to be immune to the predations of rabbits[233].
