Description

A member of the buttercup family, monkshood is native to the eastern US.  It is listed as endangered in five states.  It is suitable for a variety of soil textures, including heavy clay, provided a moist environment is present.  Dappled shade is ideal. 

The growth habit may inhibit the health of surrounding plants. Resembling a vine, it will send several arching stems upwards that will use surrounding plants for support.  These slender stems can reach lengths of up to 5'.

It can be found in the wild in low woods and damp slopes, thickets, wet areas along streams and in springs.    It does best when roots are shaded from the mid-day sun.

Although it can be propagated from seed, using caution in handling, the preferred method is by division.  Division should be accomplished in the fall after the leaves have died back. The seed may be slow to germinate.

Insects, Diseases and Other Plant Problems:  Occasional disease problems include crown rot, powdery mildew, and verticillium wilt.  All parts of this plant contain poisonous alkaloids, caution should be used when handling.
