A choice alpine perennial rising from the soil in early spring. First the foliage emerges which is deeply dissected and fern-like, colour is silvery-grey and has an unusual appearance. Each leaf is up to 8 cms long and half as wide being held on rigid petioles. Flowers are held on dainty stems, up to 4 or so per stem and is a clean white in colour. Each flower is like a small swollen pouch with two splaying petals. These last for around fourteen days each or so and are borne in succession.
