Physical Property Perennial growing to 0.3m by 0.3m. It is hardy to zone 3.The flowers are hermaphrodite and are pollinated by bees,beetles, flies. It is noted for attracting wildlife.The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil.The plant prefers acid, neutral and alkaline (basic) soils.It can grow in semi-shade (light woodland) or no shade.It requires wet soil and can grow in water.
Every part of this plant is strongly irritant and so it should be used with caution. The whole plant is anodyne, antispasmodic,diaphoretic, diuretic, expectorant and rubefacient. It has been used to remove warts and is also used in the treatment of fits and anaemia. The root is antirheumatic, diaphoretic, emetic and expectorant. A decoction is used in the treatment of colds. A poultice of the boiled and mashed roots has been applied to sores. A tea made from the leaves is diuretic and laxative. All parts of the plant can irritate or blister the skin or mucous membranes.
Cultivation A plant of the waterside, it prefers growing in a sunny position in wet soils or shallow water up to 15cm deep, though it will tolerate drier conditions if there is shade from the summer sun. Another report says that it grows best in partial shade[17]. Requires a deep rich slightly alkaline soil. 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[208]. 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.
