HELLEBORUS

This genus comprising 15 species belongs to the buttercup family (Ranunculaceae) and is found in temperate zones from Europe to western China. They are mostly low-growing plants with hand-shaped, often toothed, short-stemmed, deep green leaves that emerge from a fleshy root-stock. The simple, 5-petalled, bowl-shaped flowers appear from mid-winter through to spring and occur in unusual shades of green, dusky pink, and maroon, as well as white. At the center of the flower are prominent, green, nectar-containing sacs and a number of yellow stamens. Commonly known as the lenten rose or winter rose, the perennials of this species were favorities of Gertrude Jekyll (1843-1935), a passionate English expert gardener and designer.


CULTIVATION


Helleborus species prefer cooler climates and woodland conditions with deep, fertile, humus-rich, well-drained soil and dappled shade. Some of the smaller types of plants are suitable for rockeries. Many species benefit from having old foliage removed when the plants are dormant. Propagate by division or from seed.


Top Tip


All Helleborus species are toxic and the sap can cause skin irritation, so exercise caution when handling. Keep out of reach of children.
