Ranunculus aquatilis (common name: water crowfoot)

Propagation: Seed - sow spring in a tray of water 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. Very easy, larger 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.

Cultivation: A plant of boggy soils and shallow water, it prefers a loamy soil and a sunny position.

A greedy plant, inhibiting the growth of nearby plants, especially legumes[1].

Range: Most of Europe, including Britain.

Habitat: Ponds, ditches and streams throughout lowland Britain[2].

Edibility: The entire plant has been boiled and eaten[3]. Some caution is advised, see the notes above on toxicity.

Medicinal: The sub-species R. aquatilis capillaceus is used is used in India in the treatment of intermittent fevers, rheumatism and asthma[4].

Pollinators: Flies, bees, self

Soil: Can grow in light, medium, and heavy soils.

Flower Type: Hermaphrodite

Known Hazards: All parts of the plant are poisonous when fresh, the toxins are destroyed by heat or by drying[5][6][7][8][9]. The plant also has a strongly acrid juice that can cause blistering to the skin[9][10].

Also Known As: R. diversifolius. R. heterophyllus. R. radicans.
