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 - cooked. Steeped and boiled[177]. It can also be dried for later use[257]. The root is said to be extremely nutritious[85], though some native North American Indian tribes believed that eating it could cause insanity[257]. It is easiest to use when the plant is in flower because the outer layer of the root (which is very bitter) slips off easily at this time of the year[85]. The root has a good taste though a decided bitter flavour develops afterwards[105, 161].

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

Requires a very well-drained gritty humus-rich deep soil in a sunny position[1, 200]. Prefers a neutral to acid soil[188]. This species is not reliably hardy in Britain. It can withstand consistently very cold weather but does not like alternating periods of mild and cold conditions, nor does it like winter wet[1]. The plant is very susceptible to rotting at the neck in a damp soil[200]. Plants die down after flowering and start growing again in the autumn[188]. A very ornamental plant[1]. Polymorphic[60]. Very apt to hybridize with other members of this genus[1].

Propagation

Seed - best sown as soon as it is ripe in a cold frame in a very freely draining soil[129]. Sow stored seed as soon as possible in a cold frame. One months cold stratification should improve germination, though this is still likely to be very slow. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first two winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in March/April. Very difficult.
