Closely related to anemones, pulsatillas are perennials native to European mountain regions. Two species are suitable for rock gardens. P. vulgaris is known as the pasque flower. It is easy to grow and bears large purple flowers surrounded by a frill of fine, hairy leaves. The foliage is delicate and fern-like. P. alpina bears long-lasting white flowers flushed blue on the outside, followed by fluffy silver seedheads. Once established, both species are long-lived.

GROWING Plant in autumn in an open, sunny site on alkaline, free-draining soil. Do not disturb the plants thereafter.

PROPAGATION Sow fresh seed in summer in trays of seed compost in a cold frame. When the seedlings are large enough to handle, prick off into boxes and overwinter in the frame. Pot up individually when new leaves appear in spring. Water well as the plants develop and plant out in autumn.

VARIETIES P. vulgaris: `Rubra' (above), glowing red; `Budapest', reddish-purple. P. alpirza: `Sulphurea', sharp yellow flowers last until mid summer.

POSSIBLE PROBLEMS Generally trouble-free.
