Wow! Those are going to be stunning in bloom. I can see the fascinated stem on the last one for sure. Wonder if the first one fascinated right before starting to form buds. Can you tell if the part of the stem that the buds are formed on is flattened at all? Almost looks like it in the photo. I have seen some very strange fascinated blooms on coneflowers and other plants too. It is fun to watch for one you know what you are looking for.
