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: Root
Edible Uses:

Root?? A number of species in this genus have edible bulbs. Although no records have been seen for this species, it is fairly hardy in Britain and the root can be as large as a football. It is worthy of investigation[K].

Medicinal Uses

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

Easily grown in a moist soil or the garden border[90]. Requires a rich well-drained soil in a warm sheltered sunny position[188]. Plants are only hardy in the milder areas of the country, tolerating temperatures down to about -10°c[90]. It is probable that the plants may require winter protection with dry leaves or bracken[90]. Bulbs are sensitive to transplanting and may take several years to establish[200]. After this, they will usually reproduce rapidly from offsets to produce the overcrowded conditions that stimulate them to flower freely[200]. The bulbs should be planted with their necks above soil level[233]. This conflicts with another report which says that they should be planted quite deeply in the soil[1]. Only plant out good sized bulbs and do so at the end of May[1]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233]. The flowers emit a sweet, somewhat spicy odour which is especially pronounced at nightfall[245].

Propagation

Seed - best sown as soon as it is ripe, placing 2 - 3 seeds in individual pots in a greenhouse. Do not cover the seed. Sow stored seed April/May in a warm greenhouse. Once they have germinated, you can thin each pot to just one plant if required, though we have not found this to be necessary. Give an occasional liquid feed to ensure that the plants do not suffer nutritional deficiencies. Grow them on in the greenhouse for at least their first 2 years, planting them out into their permanent positions in the spring. Division of offsets in April/May or in September. When divided in the spring, the bulbs can be planted out direct into their permanent positions, if done in September, however, they should be potted up and overwintered in the greenhouse.
