Actaea (syn. Cimicifuga): Bugbane
In spring, while pastel colored ephemerals dominate gardens around the city, Actaeas are beginning to emerge from dormancy. Varieties with jet black foliage provide excellent color contrast for other early blooming shade beauties.
In May and June, many gardens have reached their peak of bloom, while Acteas have filled in with lacy foliage in the background. Then in July, when it is becoming difficult to find flowers in shady areas, long spikes of fragrant white flowers which glow shockingly bright and seem to float in midair. The return of cool weather brings drying seed heads, their spiky outline still visible.
Black foliaged varieties are even darker when grown in full sun (with adequate water). Into the fall their foliage, black, and reliable as ever, lends beauty to late season interest plants such as Fuchsias, Aconitum, and grasses.
Green foliage varieties are less tolerant of hot sun, but continue to add height and texture to shade gardens until November. They combine well with hostas, calla lilies and black mondo grass.
Did you know? Bugbanes have recently been reclassified from Cimicifuga to Actaea. However they have been classified, they have been admired for many decades. Native Americans used Actaea racemosa (Black Cohosh) for snake bites, and it continues to be used in modern herbal medicine for a variety of ailments.
