Uses

Toxic parts

The whole plant, but especially the older portions, contains the toxic glycoside protoanemanin - this is destroyed by heat[1]. The sap can irritate sensitive skin[1].

Edible uses

Notes

Root - it must be well cooked[1]. Some caution is advised, see the notes above on toxicity. Flower buds - raw, cooked or pickled and used as a caper substitute[2][3][1][4]. Some caution is advised, see the notes above on toxicity. Young leaves, before the flowers emerge are eaten raw or cooked[2][1][4]. Some caution is advised, see the notes above on toxicity. Older leaves, before the plant flowers, can be eaten if well cooked[2]. Some caution is advised, see the notes above on toxicity.

Propagation

Seed - best sown as soon as it is ripe in a cold frame in late summer[6]. Stand the pots in 2 - 3cm of water to keep the soil wet. The seed usually germinates in 1 - 3 months at 15°c[7]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a tray of water in a cold frame until they are at least 15cm tall. Plant them out into their permanent positions in the summer. Division in early spring or autumn[6]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring.

Cultivation

A plant of the waterside, it prefers growing in a sunny position in wet soils or shallow water[8][9][10], though it will tolerate drier conditions if there is shade from the summer sun[10]. It requires a deep rich slightly acidic soil[9][6]. Grows well in heavy clay soils. Plants are hardy to about -20c[11]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[12].
