Think I got mine from Brent and Becky's Bulbs--I highly recommend them. It didn't like it here and melted when we got our normal hot and humid weather. I see Plant Delights also lists them, and I have been pleased with what I got from them too--and they say it's only grown to z8. Too often what happens here! Guess I should have checked their site before I ordered it--they seem to be very good about zone recommendations.
