Northern blue monkshood is a threatened, native perennial wildflower of the buttercup family, known for blue helmet-shaped flowers on stems up to about 1.2 m tall. It needs cool, moist, shaded conditions, so it is rarely grown outside its native habitat and is best left to naturalist or conservation gardens.

About

Aconitum noveboracense, also known as northern blue monkshood or northern wild monkshood, is a flowering plant belonging to the buttercup family (Ranunculaceae). Members of its genus (Aconitum) are also known as wolfsbane.

A. noveboracense is listed as a threatened species by the United States Fish and Wildlife Service. The species can only be found in Iowa, Wisconsin, Ohio, and New York, and populations have been in decline since the 1980s. A narrow set of environmental conditions for growth limit the plant to these areas, so a species recovery plan has been set in place to preserve the populations in these habitats.

Where it grows

Most populations of Northern Monkshood plant are found in northeastern Ohio, and portions of the "Driftless Area" located in northeast Iowa and southwest Wisconsin. Only seven populations of the plant can be found in the Catskill Mountains of New York State.
