I grew mine from seeds I got in a trade years ago. I had two, and they never bloomed, so I moved one of them to see if it made a difference, and it surely did. It is the only one that blooms. The other is under an oak, so I think it doesn't get enough sun. I can't move it now, because of the root system intertwining with the oak's. I didn't know they could be grown from cuttings. I'll try that this spring.
