Noteworthy Characteristics

Actaea racemosa, commonly called black cohosh, is an upright, Missouri native perennial which occurs in rocky woods in the Ozark region of the State. It typically grows to a total height (foliage plus flowering spikes) of 4-6’, but under optimum conditions can reach 8’. Small, numerous, creamy white, fragrant flowers appear in late summer to early fall in long, terminal racemes resembling fluffy spires (typically 1-2’ long) rising well above the foliage on wiry stems. Astilbe-like, deeply cut, tripinnate foliage is an attractive deep green. Synonymous with and formerly known as Cimicifuga racemosa. All plants in the genus Cimicifuga have recently been transferred to the genus Actaea.

Genus name is the Latin name adopted by Linnaeus from Pliny.

Specific epithet refers to the flowers being produced in racemes.

The common name of bugbane is in reference to the odoriferous insect repellant properties of this plant. Cohosh comes from an Algonquin word meaning rough in reference to the appearance of plant rhizomes.
