Rick , You are right. It is "double cellona". I Google it and you are correct. Someone actually posted a photo on Cacti and Succulent forum on garden web in 2011 which looks just my like my plant. Thank you all for your comments and help.

Don't forget to add BRUNFELSIA right next to No# 1, next to Bouvardia! The best thing about Brunfelsia is that it is much more hardier than the Bouvardia. Great job with this list considering I am well on my way to having them all:-) Mike

You don't graft, or T bud, using a flower bud. You use a vegetative bud. The picture shown is of a T bud. You insert a vegetative bud if you want a tree. It has to be done when bark is slipping on the rootstock. That's usually June thru August. In long season areas May to Sept. Never had disease due to cuts. Not on the cut end or area of the bud or graft.

Marcia, it would only change the possibilities of what you might get from seeds if one of the blooms was pollinated. Then, chances of prospective seedlings of said seed would still be different from either pod or pollin parent. Many of the flowers only have the receptive part and not the pollin. Rick
