Hillside Black Beauty Bugbane

Cimicifuga ramosa 'Hillside Black Beauty'

The Story

Plant Bio

Actaea, commonly known as bugbane, are elegant, clump-forming woodland perennials valued for their dramatic, finely-cut foliage and tall, fragrant flower spikes.

'Hillside Black Beauty' is renowned for its exceptionally dark, deep purple-black, lacy foliage that holds its color well, providing a stunning backdrop for its fragrant, bottlebrush-like white flowers.

Uses & Benefits:

Offers season-long drama with its deep purple-black, finely-cut foliage. In late summer, it produces tall, fragrant, creamy-white flower spires that create a stunning contrast and provide vertical interest.

Its large size and bold texture make it an excellent background plant or specimen in a shade or woodland garden. The foliage provides a dramatic foil for plants with gold, chartreuse, or blue leaves.

The late-season flowers are a crucial nectar source for bees, butterflies, and other pollinators when many other plants have finished blooming, supporting biodiversity in the garden.
