Jan you are correct most need to keep potted and bring in in winter. I live in the orlando area I leave mine out all year BUT bring in when they call for frost and freeze. I am looking at getting them from Thailand and there are so many kinds the problem is min order and most the doubles are at-least a 60 -90 day wait to get them. The regular ones don't take that long. min orders on most of the hybrids are 100 per case. the older 2-3 or 4-5 yo branched are 20-25 per case. they would be coming from the same company in Thailand that we got our grafted plumeria in last co-op BUT im getting all the info BEFORE opening the co-op no confusions this time.
This is a pic of sisters bloom
I will get more info in the next two days
