Sounds like you all are getting off to a good start, great choices! I have made many purchases off eBay and most have done well, several good websites have gotten their start on eBay.
PowWow Berry is wonderful, I just bought a second one, also two PowWow white, my other one died last year because of root-rot, I had poor drainage in the side flower bed and have started a new flower bed out back with better drainage and more sun. They really like that!
I also have gotten Hot summer, Flame Thrower, Fragrant Angel, Sundown, Hot Papaya, Green Envy, and when I ordered White Swan they sent me a pink flower by misteak, it might be Southern Bell or Raspberry Truffle, it's beautiful what ever it is, and I want more!
