Cowflock

A plant of the waterside, it prefers growing in a sunny position in wet soils or shallow water up to 15cm deep[1, 111, 233], though it will tolerate drier conditions if there is shade from the summer sun. Another report says that it grows best in partial shade. Requires a deep rich slightly alkaline soil[31, 111]. Grows well in heavy clay soils. Prefers a chalky soil. Tolerates a pH in the range 4.8 to 7.5. A very ornamental and polymorphic plant, there are some named varieties. Plants often self-sow when well sited. A good bee plant. A greedy plant, inhibiting the growth of nearby plants, especially legumes. This species is probably the most primitive flower in the British flora.

Edible Parts: Flowers Leaves Root Edible Uses: Root - must be well cooked. 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[142, 183]. Eating the raw flower buds can lead to intoxication. Some caution is advised, see the notes above on toxicity. Young leaves - raw or cooked[2, 46, 55, 62, 161]. 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[2, 183]. Eating the raw leaves can lead to intoxication. Some caution is advised, see the notes above on toxicity. Older leaves, before the plant flowers, can be eaten if they are well cooked. Some caution is advised, see the notes above on toxicity. References More on Edible Uses

Seed - best sown as soon as it is ripe in a cold frame in late summer. Stand the pots in 2 - 3cm of water to keep the soil wet. The seed usually germinates in 1 - 3 months at 15°c. 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. 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.
