There has been a great deal of confusion between the similarities oi Actaea and Cimicifuga because many of the species are so alike. DNA analysis combined with many similarities between the two groups does not keep Actaea and Cimicifuga separate. Overall the classification is now known as Actaea.Actaea are a long-lived perennial comprising 28 species from North America, Europe and Asia. Five species formed the original group and these all produce white, red and black berries. The original species are mainly woodland plants. The other 23, which were recognised as Cimicifuga, form seeds in capsules. One particular species, A. racemosa Award of Garden Merit (AGM), comprises a cross between the two— dry capsules and a fleshy berry.
