Pulsatilla vulgaris

Pulsatilla vulgaris (pasque flower, pasqueflower, common pasque flower, European pasqueflower, Dane's blood) is a species of flowering plant belonging to the buttercup family (Ranunculaceae), found locally on calcareous grassland in Europe. It used to be considered part of the Anemone genus, to which it is closely related.
It is classified as a Priority Species in the UK Biodiversity Action Plan and as Vulnerable in Britain on the Red Data List.

This is an herbaceous perennial plant. It develops upright rhizomes, which function as food-storage organs. Its leaves and stems are long, soft, silver-grey and hairy. It grows to 15–30 cm high and when it is fruit-bearing up to 40 cm. The roots go deep into the soil (to 1 m). The finely-dissected leaves are arranged in a rosette and appear with the bell-shaped flower in early spring. The purple flowers are followed by distinctive silky seed-heads which can persist on the plant for many months.

The flower is 'cloaked in myth'; one legend has it that Pasque flowers sprang up in places that had been soaked by the blood of Romans or Danes because they often appear on old barrows and boundary banks.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.

It grows in sparsely wooded pine forests or meadows, often on a sunny sloping side with calcium-rich soil. A large colony occurs on publicly accessible land in the Cotswolds, at the Gloucestershire Wildlife Trust's Pasqueflower reserve.

It has a thick and somewhat woody root-stock, from which arises a rosette of finely-divided, stalked leaves, covered with silky hairs, especially when young, the foot-stalk often being purplish. 


The flowers, which are about 1 1/2 inches across, are borne singly on stalks 5 to 8 inches in height, with an involucre of three sessile (i.e stalkless) deeply-cut leaflets or bracts. The sepals are of a dull violet-purple colour, very silky on the under surfaces. The seed- vessels are small, brown hairy achenes, with long, feathery tails, like those of the Traveller's Joy or Wild Clematis.

The whole plant, especially the bases of the foot-stalks, is covered with silky hairs. It is odourless, but possesses at first a very acrid taste, which is less conspicuous in the dried herb and gradually diminishes on keeping. The majority of the leaves develop after the flowers; they are two to three times deeply three-parted or pinnately cleft to the base, in long, linear, acute segments.

The juice of the purple sepals gives a green stain to paper and linen, but it is not permanent. It has been used to colour the Paschal eggs in some countries, whence it has been supposed the English name of the plant is derived. Gerard, however, expressly informs us that he himself was 'moved to name' this the Pasque Flower, or Easter Flower, because of the time of its appearance, it being in bloom from April to June. The specific name, pulsatilla, from pulsc, I beat, is given in allusion to its downy seeds being beaten about by the wind.


Varieties of pulsatilla when cultivated in this country like a well-drained, light, but deep soil, and will flourish in a peat or leaf soil, with the addition of lime rubble.
