Brown-eyed Susans are often called thinleaf coneflower. The brown-eyed epithet seems to be taking over. It's just more fun. Who cares about allegedly thin leaves?
Ives Preserve has had no brown-eyed Susan. We had seen this native within a couple hundred yards of the Preserve, but not in it. So we fixed that, and brought them in. It seems a little strange and somehow dishonest to do that. On the other hand, one more species is preserved, and we have got the old gravel pit to repopulate. They do seem to be happy there.
