An outstanding perennial which produces Thalictrum-like leaves numbering up to 9 per stem. This relatively double flowered form is a garden hybrid which stands up well in poor conditions. Flower colour is pure white throughout. Leaf petioles arise directly from the tubers which lie just below the soil surface. Leaflets are rounded, slightly serrated and deep green in colour. Flowers are somewhat delicate in appearance but resilient enough to last for several weeks, even in poor weather. Each stem may carry up to 4 flowers which tend to open in quick succesion. Best suited to a shadier area of the rock garden or a woodland situation.
