Monk's-hood

Aconitum napellus, monkshood, aconite, Venus' chariot or wolfsbane, is a species of highly toxic flowering plants in the genus Aconitum of the family Ranunculaceae, native and endemic to western and central Europe. A perennial plant, it is herbaceous and grows to 1 m (3 ft 3 in) tall, with hairless stems and leaves. The leaves are rounded, 5–10 cm (2.0–3.9 in) diameter, palmately divided into five to seven deeply lobed segments. The flowers are dark purple to bluish-purple, narrow oblong helmet-shaped, 1–2 cm (0.39–0.79 in) tall. Plants native to Asia and North America formerly listed as A. napellus are now regarded as separate species. The plant is extremely poisonous in both ingestion and body contact. It is the most poisonous plant in all of Europe.
