A super perennial which produces Thalictrum-like leaves numbering up to 9 per stem. 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 cup shaped, somewhat delicate in appearance but resilient enough to last for several weeks, even in poor weather. Flower colour is usually white but occasional a pale pink colour may appear. Each stem may carry up to 4 flowers which tend to open in quick succession. Best suited to a shadier area of the rock garden or a woodland situation.
