Requires a moist or wet fertile soil in a sunny position. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c.

Root. Starchy with a flavor somewhat like filberts, is much esteemed in some areas. Some caution is advised since many members of this genus are very poisonous, see the notes above on toxicity.

Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn. Very easy, large divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Meadows and damp grassy places.
