About Pulsatilla halleri (All.) Willd.
Pulsatilla halleri, synonym Anemone halleri, common name Haller's anemone, is a species of flowering plant in the buttercup family Ranunculaceae. It can be found in sub-alpine and alpine regions starting from southern France, southern Switzerland, northern Italy and Poland, extending east to Greece, Bulgaria and Ukraine. Its native habitats include mountain meadows, dry hills, dry grassy locations and mountainous forest glades. It is collected and cultivated for use in botanical and private gardens. This herbaceous perennial grows in clumps reaching 20 cm, or 7.9 inches, tall and wide. It has hairy grey-green foliage, and in spring it produces pink or purple flowers that later form ornamental silky seedheads. It prefers an exposed, well-drained position in full sun. Anemone halleri is mildly toxic, and can cause stomach ache after skin contact. Both the full species and the subspecies P. halleri subsp. slavica have received the Royal Horticultural Society's Award of Garden Merit.
