Hellebores are toxic! All parts of the plant are toxic to some extent. This plant is said to have been used as the first chemical warfare; it is said ancient Greeks used hellebore plants to poison the city water supply of their enemies and this caused all in the town to die. This plant was also used to make poison to put on the tips of arrows to make the arrows more deadly. This plant also had medicinal "properties"...such as a cure for insanity. There are several species (subspecies?) of hellebores, and while some species are more toxic than others, all hellebores appear to be toxic to some extent. PLEASE be careful with this plant around pets and small children. Do not let pets or children chew on these plants.

GROW THIS PLANT! It has lovely flowers at the time of year we need them most that last up to 6 weeks-- tons of colours and cultivars! The foliage is quite attractive and en masse, this plant is like a Pachysandra with personality!
Downside-- Germination of seed takes up to 3 years. Buy nursery grown stock or cuttings. It can be expensive to get a grown cover effect :(
A clump forming, variable perennial, parents are H. orientalis and other species of Helleborus.
Has leathery, toothed, dark green, pedate leaves. Bears long lasting, saucer shaped, 5 petalled, green, white, pink, cream, purple or yellow flowers sometimes mottled with another colour up to 3 inches across.
