Northern monkshood

Scientific Latin name: Aconitum noveboracense

Status: Threatened in the U. S. and Iowa

Description: Northern monkshood is a Pleistocene (Ice Age) relict. It is noted for its very distinctive, blue hood-shaped flowers. The flowers are about one inch in length, and a single stem may have many flowers. Stems range from about one to four feet in length. The leaves are broad with coarse, toothed lobes.

Habitat: A member of the buttercup family, northern monkshood’s preferred habitats are cold stream beds, mossy banks, cliffs, slopes, and cold woods. Northern monkshood almost always grows with cold air drainage or cold water flow nearby. The seeds of monkshood are likely spread by water flow within the tributary watersheds.

Current Iowa range: Allamakee, Clayton, Delaware, Dubuque, Jackson and Hardin counties.
