Uses

Toxic parts

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

Edible uses

Notes

Root - must be well cooked[2]. The raw root should not be eaten[K]. Some caution is advised, see the notes above on toxicity.

Flower buds - raw, cooked or pickled and used as a caper substitute[3][2]. Eating the raw flower buds can lead to intoxication[4]. Some caution is advised, see the notes above on toxicity. Young leaves - raw or cooked[5][6][7][8][9]. The leaves are harvested in the spring as the plant is coming into flower and is used like spinach after cooking in two or more changes of water[5][2]. Eating the raw leaves can lead to intoxication[4]. Some caution is advised, see the notes above on toxicity.

Older leaves, before the plant flowers, can be eaten if they are well cooked[1]. Some caution is advised, see the notes above on toxicity.

Flowers

Leaves

Material uses

A yellow dye is obtained from the flowers[[10][11], a saffron substitute[3]. It is used as a dye when mixed with alum, though it is not very permanent[12]. Plants can be grown for ground cover when planted about 45cm apart each way[13].

Medicinal uses(Warning!)

Every part of this plant is strongly irritant and so it should be used with caution[12].

The whole plant is anodyne, antispasmodic, diaphoretic, diuretic, expectorant and rubefacient[14][1]. It has been used to remove warts and is also used in the treatment of fits and anaemia[12][14][1]. The root is antirheumatic, diaphoretic, emetic and expectorant[15][4]. A decoction is used in the treatment of colds[16]. A poultice of the boiled and mashed roots has been applied to sores[16]. A tea made from the leaves is diuretic and laxative[4][16].

All parts of the plant can irritate or blister the skin or mucous membranes[4].

Propagation

Seed - best sown as soon as it is ripe in a cold frame in late summer[17]. Stand the pots in 2 - 3cm of water to keep the soil wet. The seed usually germinates in 1 - 3 months at 15°c[18]. 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[17]. 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 up to 15cm deep[19][20][21], though it will tolerate drier conditions if there is shade from the summer sun[21]. Another report says that it grows best in partial shade[22]. Requires a deep rich slightly alkaline soil[23][20]. Grows well in heavy clay soils. Prefers a chalky soil[23]. Tolerates a pH in the range 4.8 to 7.5.

A very ornamental[19] and polymorphic plant[22], there are some named varieties[21]. Plants often self-sow when well sited[13]. A good bee plant[24]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[25].

This species is probably the most primitive flower in the British flora[22].
