Black Baneberry Actaea racemosa LinnaeusSynonyms: Black Cohosh,  Cimicifuga racemosa.

Status:

Black Baneberry is found throughout the western shore of Maryland. While rare on the coastal plain, Black Baneberry becomes more common in the Ridge and Valley and Allegheny Plateau.

Description:

Black Baneberry flowers from the end of June through mid-May. Black Baneberry is very similar to the rare Mountain Bugbane. Both plants have tall narrow spikes of white flowers. According to Weakley (2015) the two species can be told apart by looking at the petioles of the basal leaves: Mountain Bugbane has a deep broad groove that runs the length of the petiole while the petiole of Black Baneberry has no groove. The other Actaea species White Baneberry has a smaller spike of white flowers that is more rounded than long. The mature fruit of White Baneberry is bright white while the fruit of Mountain Bugbane and Black Baneberry are black when mature.

Relationships:

Black Baneberry is a larval host for the butterfly Appalachian Azure.
