Kew Species Profiles

General Description
Haller's anemone is insulated with dense hairs, allowing it to grow even in freezing temperatures.

Anemone halleri is a beautiful, early-flowering perennial with pale blue or lavender flowers, covered on the outside with white or golden, silky hairs.

Haller's anemone belongs to a group of early-flowering perennials (commonly referred to by the synonym Pulsatilla and including those with the common name pasque flower) found across the entire northern hemisphere, from eastern China to western North America. The flowers, which are purple, white, yellow or reddish, emerge in spring, before or with the leaves. They are followed by fruits with a long, silky, persistent style. It is one of the most beautiful Anemone species, with upright flowers and often woolly stems and grows in scattered localities from France eastwards to the Crimea.

Species Profile
Geography and distribution

Native to south-eastern France, southern Switzerland and Poland, extending eastwards to Greece, Bulgaria and the Crimea.

Description

A long-lived, low-growing perennial with deep roots. The leaves are woolly, mostly basal and pinnate, with three to five main segments, the terminal segment having a long stalk. The flowering stems are about 5 cm tall at the time of flowering, elongating later. The stem leaves are thread-like and are borne in a ring below the flower. The flowers are pale blue or purple, with six petals, 6-8 cm across. The flowers have many yellow anthers and many stigmas, the silky styles persisting to form a 'sail' which aids dispersal of the fruits.

Threats and conservation

Not known to be threatened, but vulnerable to changes in the management of pastures.

Uses

Anemone halleri is cultivated as an ornamental. Several subspecies have been described and are available commercially.

Cultivation

Anemone halleri requires soil with good drainage, and the hairier forms benefit from protection from rain during warm, wet winters.
