Ornamental features

Black Negligee Bugbane features bold spikes of fragrant white flowers with shell pink overtones rising above the foliage from mid to late summer. The flowers are excellent for cutting. Its attractive deeply cut ferny compound leaves emerge dark green in spring, turning deep purple in color with hints of black throughout the season. The brown fruits are carried on spikes from late summer to late winter. The deep purple stems are very colorful and add to the overall interest of the plant.

Planting and growing

Black Negligee Bugbane will grow to be about 3 feet tall at maturity extending to 5 feet tall with the flowers, with a spread of 3 feet. It tends to be leggy, with a typical clearance of 1 foot from the ground, and should be underplanted with lower-growing perennials. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant performs well in both full sun and full shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selection of a native North American species. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
