Thanks Marilyn, Kermit & Debra!
I know renaming happens a lot with trademarked names especially. Some plants end up with several monikers because companies want to make money off the trademark and deceive people into thinking that it's a new variety. However, the name 'Cislano' doesn't really sound like the typical, cutesy marketing name so it may be a legit cultivar.
'Cislano' is a purple calyx/purple flower variety. It has some flowers on it at the moment but it won't really show its best color until the fall, I'm sure. Sadly, 'Midnight' and 'Santa Barbara' are no longer with me so I can't do a direct comparison to them.
