I received this from Yardbird. I have taken several cuttings, which so far, appear to being doing well. Make a note to yourself to email me around April and I will try and get you one. Doesn't Yardbird do good :-) LOL
I just wish I had your zone, it would have lasted longer.
No, I've never grown them from seed. This is my first one and I received it from Yardbird. I have taken cuttings of this though. Come to think of it, I don't remember seeing any seeds. I'm sure there had to be some though, eh?
