A low growing tuberous perennial, which is much-loved for its large, black-eyed, violet-blue flowers, which appear in spring over mounds of finely dissected foliage. The velvet-like petals form large open bowls, and gradually open out even further before they fall to create saucer-like plates. They make charming cut flowers and look lovely at the front of a sunny border.
Garden care: Plant pre-soaked tubers 5-8cm (2-3in) deep and 15cm apart in September or October in light, sandy soil in a sunny, protected site. Cover with a cloche or dry mulch to protect against extreme winter weather.
