Plant Common Name
Rock and Roll Astilbe
General Description
This astilbe, ‘Rock and Roll’ is a herbaceous perennial grown for its tolerance of shade, dependable bloom, spikes of flowers, and dark, dense ferny foliage. The spikes have a branching habit, a bit like a Christmas tree. Tiny, closely packed flowers clothe the spikes, transforming them into soft, billowing plumes. One plant may produce several, making a cloud of bloom above the leaves. A member of the Music Series, ‘Rock and Roll’ blooms with white flowers in mid through late summer. Deadhead the plant after the first flush of flowers; you may be rewarded with a second bloom in autumn.
Astilbes prefer partial shade and fertile, well-drained, moist soil. Plant ‘Rock and Roll’with other members of the Music Series such as 'Jump and Jive' and 'Drums and Bass' in a shady, woodland border. Like most astilbes it also is a good companion for hostas and ferns.
