Cohosh comes from an Algonquin word meaning rough in reference to the appearance of plant rhizomes.
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 inch, but under optimum conditions can reach 8 inch.
Small, numerous, creamy white, fragrant flowers appear in late summer to early fall in long, terminal racemes resembling fluffy spires (typically 1-2 inch long) rising well above the foliage on wiry stems.
