Pulsatilla alpina subsp. alpina

The Pulsatilla genus includes some of the loveliest of all flowering plants. In early spring when their woolly, flower buds first appear, through to flowering-time, their beautiful flowers will attract praise from all that see them.
From the time their enchanting, feathery seed-heads are formed, through to autumn, their hairy foliage always looks attractive. These plants are always a delight. The flowers become silky fruiting seed-heads which are interesting in the garden and are also good for flower arrangements.

Pulsatilla alpina subsp. alpina is a true alpine, its size and shallowly cup-shaped blooms makes it a favourite for alpine collectors. Also called the Alpine Pasqueflower or Alpine Anemone, this charming white form subsp. alpina has white flowers, the outer segments flushed with bluish-purple. With a protracted flowering period and followed by attractive seed heads, they are showy, long-lived and reliable plants with a lengthy period of interest.
Native to the mountain ranges of central and southern Europe and the Caucasus. The common name of Pasque Flower comes from the French word Pâques, meaning Easter, the time of year when Pulsatilla bloom. The flowers are produced very early, often opening while still under snow cover.

Hardy and long lived. Pulsatilla are an easy plant to grow, the plants can develop into robust clumps after only a few years, with a dozen or more blooms out at any one time. They are an almost essential plant for the rock garden as they will tolerate a range of conditions and really hard winters.
The plants grow to a height of 15 to 30cm (6 to 12in) tall, and a spread of 20cm (8in). They are excellent at the front of the perennial border or cold greenhouse, and can also be shown off planted in pots and containers, their main requirement is a well-drained soil. But be aware, pulsatilla do not like to be pot-bound.

Sowing:
Sow in late winter to early spring, February to April or sow in late summer to Autumn, August to October.
Trim any of the tails that are left on the seed and sow on the surface of lightly firmed, moist seed compost in pots or trays. Just cover the seed with a light sprinkling of compost or vermiculite. After sowing, do not exclude light as this helps germination.
Keep at a temperature of between 15 to 20°C (59 to 68°F). Keep the surface of the compost moist but not waterlogged; germination is erratic, taking between 30 to 180 days. The seed may germinate after a couple of weeks in summer or sometimes will appear in spring after going through the winter following sowing.
When the seedlings are large enough to handle, carefully transplant the seedlings into 7.5cm (3in) pots to grow on. Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out. While the seedlings can be moved when young, but established plants have long, fleshy taproots and don’t like being disturbed.
Plant 30cm (12in) apart. For best results, provide well-drained soil in full sun.

Cultivation:
As long as the plants are given a fertile, gritty, well-drained soil in full sun they should be long-lived. If the plants are left with wet roots over winter they are likely to rot and die.
There are no particular pests or diseases affecting Pulsatilla, apart from slugs and snails, which can feast on emerging buds.
The roots are easily damaged, so digging and dividing your Pasque Flowers should only be done when absolutely necessary and then, it should be done during the winter. Root cuttings can be taken at that time.
The plants self-seed readily and their seedlings can be transplanted to a permanent spot easily while they are still young.
The plants go dormant in mid-summer, so be sure to mark the planting spot with a stake as they disappear from sight so that you don't accidentally dig them up.

Please Note:
Pulsatilla flowers and seed are toxic and are not to be eaten. The plant is a member of the same family as Buttercup and contains the glycoside ranunculin. It has a very bitter taste which produces an immediate burning in the mouth. Fatal in a large amount but there are no records of anyone ever consuming enough because of the taste and effect.

Plant Uses:
Alpines and Rockeries, and Flower Borders and Beds. Containers and Troughs.

Origin:
Most of the 30-plus species of Pulsatilla are found in Europe and temperate Asia, but their range extends as far east as Japan, and two species occur in North America. Pulsatilla alpina is native to the mountain ranges of central and southern Europe, from central Spain to Croatia. It can be found at altitudes of 1,200 to 2,700m (3,900 to 8,900ft). It thrives on dry, sunny, infertile meadows and grassland on south or south west facing slopes. It cannot survive on fertile ground and disappears at once if the ground is fertilised. In Switzerland, all species of Pulsatilla are protected by law.
Two subspecies are well defined; subsp. alpina has white flowers, the outer segments flushed with bluish-purple, usually on alkaline soils; subsp. apiifolia (syn. P. sulphurea) has pale yellow flowers and usually occurs on acid soils.
A number of subspecies are recognised, based largely on the form and hairiness of the leaves. P. alpina subsp. schneebergensis is endemic to the easternmost Alps of Austria, and is named after the Schneeberg mountain. It is replaced further west by the widespread taxon P. alpina subsp. alpina. P. alpina subsp. austroalpina is found in the Southern Alps from Switzerland eastwards, most commonly over dolomite. P. alpina subsp. apiifolia and P. alpina subsp. alba grow over siliceous rock, but are easily distinguished by the flower colour. Further subspecies have been named for local variants in the Cantabrian Mountains (subsp. cantabrica) and Corsica (subsp. cyrnea).

Nomenclature:
The genus name Pulsatilla is derived from the Latin pulsare meaning to pulsate in reference to the movement of the flowers in the wind.
The species name alpina refers to a plant that grow in alpine areas. A true alpine is defined as a plant growing above the treeline.
It is also called the Alpine Pasqueflower or Alpine Anemone
The old English common name was originally ‘pass flower’, adopted from the French ‘passe fleur’. Gerarde changed it to ‘Pasque Flower’ from the French word Pâques, meaning Easter, the time of year when Pulsatilla vulgaris blooms.
In North America they’re sometimes classified as anemones and in Europe, Pulsatilla vulgaris was named Anemone pulsatilla by Carl Linnaeus in the 18th century. Recent phylogenetic studies, which look at DNA to establish relationships, have suggested they should be included within the genus Anemone, but for now, at least, the name Pulsatilla is the one you’re more likely to come across.
The common name for both anemones and pulsatilla is Wind Flower. The Greek physician Theophrastus (3rd century BC) named the plant ánemos, meaning wind, in reference to the shaggy little fruits that are dispersed by the wind.
It is a member of the Buttercup family, Ranunculaceae.
