Description

A herbaceous perennial that grows well in full sun in cooler climates.  It will need some afternoon shade in its southernmost range, and nighttime temperatures in the 70's.  If grown in areas where the summer temperatures are higher, the plant will require more shade.  However, when it receives too much shade, staking may be required.  The ideal situation is where the plant receives morning sun and afternoon shade.  The soil must remain moist, but not wet.  Wet soil will drown the fragile roots.

It can typically be found growing in forests, natural areas, moist woods and sitting along creek banks.  Propagation can be done in the fall by division, however, new plants are slow to become established.

Although used in the landscape, Monkshood is poisonous, with a narcotic juice present in the leaves and roots. Do not plant near the vegetable garden, where its fleshy roots could be mistaken for Jerusalem artichokes.  Wearing gloves is advisable when handling this plant.

After flowering, cut the plants back to promote re-blooming.

Insect, Disease and Other Plant Problems:  Crown rot, powdery mildew, and verticillium wilt can affect this plant.
