General Culture:

Best grown in humusy, organically rich, medium moisture, well-drained soils in part shade to full shade. Seems to grow well in average garden soils, however, as long as soils are kept consistently moist. Foliage tends to scorch or otherwise decline if soils are allowed to dry out. A slow-to-establish plant.

Noteworthy Characteristics:

‘White Pearl’ is an erect, clump-forming bugbane cultivar which is noted for its large, arching, bottlebrush-like flower spikes of pure white flowers and its late season bloom. Features ternately compound, medium green leaves on branched, dark stems typically growing to 2.5-3’ tall. Fern-like foliage usually remains attractive throughout the growing season. Flower stems arch above the foliage clump to a height of 3-4’ from late summer into autumn and feature wand-like, terminal racemes (to 24” long) of fragrant, apetalous, fluffy white flowers. Blooms somewhat later than many other species of Actaea. The common name of bugbane is in reference to the odoriferous insect repellent properties attributed to most plants in the genus. Synonymous with and formerly known as Cimicifuga simplex ‘White Pearl’. All plants in the genus Cimicifuga have recently been transferred to the genus Actaea. Species name honors J. Matsumura.

Problems: Click for detailed list of pests and problems.

No serious insect or disease problems. When in bloom, flower spires usually do not require staking, but may benefit from some support particularly if not growing in a sheltered location. Flower spires tend to bend toward bright light, particularly when plants are grown in substantial shade. Leaf margins may brown up (scorch) and growth may slow down if soils are not kept consistently moist.

Uses:

Flower spires add architectural height to shaded borders, shade gardens, woodland gardens, cottage gardens or naturalized areas. Ferny foliage provides excellent texture and color to the landscape. Best in groups, although single plants can have good specimen value once established.
