Are the buds on the black cohosh roots always purple? I dug some that have a more yellow/off white bud, but the color somewhat resembles what the bottom of some of the purple buds look like. The roots all look the same otherwise, and the tops all look the same too. They have all had tall remnant flower stalks. We have also been seeing some white bugbane, or doll's eyes, and have been meaning to dig up one of those to see the roots, but haven't. I have yet to see the 2 growing side by side. I noticed that the doll's eyes has dry flower stalks that are 1) shorter and 2) the stem from where the flower was is longer. Also, the black cohosh tend to be taller overall. My Newcomb's says that White baneberry is 1-3ft high with 1-2\" long flower racemes. Black cohosh is listed as being 3-8ft high with flower racemes that are 6\"+. So, according to my field id and book id, what I harvested should be black cohosh. Just looking for a second opinion.
