I have several purple and white plicatas that have totally confused me and will probably remain noids.
@Lestv Leslie, the Acoma you sent me did indeed match one of my noids, but not the one we thought. I knew I had another very similar plicata, and moved it to the same bed. It hadn't bloomed yet and I had forgotten about it. The Acoma you sent and that one bloomed at the same time, and both had a purple tint around the green buds and looked identical in bloom. The one we both thought was probably Acoma has no purple tint around the buds, and has less striking lines at the hafts and a slightly softer colored beard, as well as coming into bloom just as Acoma was fading. Photos coming soon
