Dear group,
I recently purchased something called scabiosa 'butterfly blue'. I had thought that this is the same as scabiosa columbaria 'butterfly blue' but was told the former is not the same as the latter. I googled 'scabiosa butterfly blue' and three names popped up: scabiosa 'butterfly blue', scabiosa columbaria 'butterfly blue', and scabiosa caucasica 'butterfly blue'. Are there any noticeable differences among them? If so what are the differences? I'm a bit frustrated with myself that I can't get a grasp around the naming convention. Thank you for your help.
Sincerely,
A.
