Abstract is: Aconitum (/ˌækəˈnaɪtəm/), also known as aconite, monkshood, wolf's-bane, leopard's bane, mousebane, women's bane, devil's helmet, queen of poisons, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia; growing in the moisture-retentive but well-draining soils of mountain meadows. Most Aconitum species are extremely poisonous and must be handled very carefully. Several Aconitum hybrids, such as the Arendsii form of Aconitum carmichaelii, have won gardening awards—such as the Royal Horticultural Society's Award of Garden Merit. Some are used by florists.
