- Description
-
Eastern blue monkshood is a member of the buttercup family (Ranunculaceae) and is native to the Eastern United States. It is most often found in the mountains, occasionally in the Piedmont but not in coastal areas. It is listed as endangered in five states and as vulnerable in North Carolina.
It is suitable for a variety of soil textures, including heavy clay, provided a moist environment is present. A dappled shade is ideal with the roots shaded from the mid-day sun. The thin flexible stems have a vining habit and will grow to 5 feet, tending to lean on or twine around any plants nearby for support. Propagation is from seeds and division. Wear gloves when handling this plant due to the toxic properties of the sap. Divide in the fall or winter once the leaves have died back.
The violet-blue or lavender-blue hooded flowers appear in late summer to fall in small clusters at the tips of the stems. The leaves are 4-6 inches long and wide with 3-5 lobes and toothed margins.
Use this plant in a woodland setting, a shade garden, in a shady border, in a naturalized area and along a stream or pond. Use with caution around pets.
Insects, Diseases and Other Plant Problems: Occasional disease problems include crown rot, powdery mildew, and verticillium wilt.
