General Description

Black Negligee autumn snakeroot is a tall, striking perennial with very attractive dark foliage from eastern Asia. Its leafed purple flowerstalks are topped by arching racemes of clear white flowers in autumn. These are borne above clumps of ashy dark purple foliage with toothed leaflets.

'Black Negligee' prefers fertile, well-drained soil with humus and a partially shaded, evenly moist location. A graceful plant, it may need staking to best show off its form, especially in windier locales when flowering begins. The striking foliage of this selection of autumn snakeroot would be stunning when placed behind bright green-leaf hostas, foamy flowers or ferns. It is also considered deer and rabbit pest resistant.
