Uses

Toxic parts

The plant contains calcium oxylate crystals. These cause an extremely unpleasant sensation similar to needles being stuck into the mouth and tongue if they are eaten but they are easily neutralized by thoroughly drying or cooking the plant or by steeping it in water.

Edible uses

Notes

Root. Considered to be edible once it has been dried, aged and elaborately processed[1]. The root contains calcium oxalate crystals - these are destroyed by drying the plant or by thorough cooking[K].

Propagation

Seed - best sown as soon as it is ripe in a shady position in a cold frame[4]. Stored seed remains viable for at least a year and can be sown in spring in the greenhouse but it will probably require a period of cold stratification. Germination usually takes place in 1 - 6 months at 15°c[4]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least a coupe of years until the corms are more than 20mm in diameter. Plant out into their permanent positions whilst they are dormant. Division of tubers when the plant dies down in late summer.

Cultivation

Prefers a cool peaty soil in the bog garden, woodland garden or a sheltered border in semi-shade[5][4][6]. Prefers a loamy or peaty soil and will tolerate a sunny position if the soil is moist but not water-logged and the position is not too hot or exposed[7][6].

Tubers should be planted about 10cm deep[8]. Only plant out full sized tubers and mulch them with organic matter in the winter[6]. Plants need protection from slugs[6].

Most species in this genus are dioecious, but they are sometimes monoecious and can also change sex from year to year.
