An E-bay Gem, Multiple Gold/J-4?
Three years ago I bought a grafted plumeria on E-bay from a Thai vendor. It was labeled as "Multiple Gold", a name I have never been able to find anywhere else. I also bought a cutting of "J-4" from another Thai vendor on E-bay and although it never grew very vigorously, it seemed to have flowers identical to the "Multiple Gold" that I bought. That one is less than 2 feet tall and seems to grow very slowly.
Strangely enough, the "Multiple Gold" seemed to grow in a very dwarf form for me, is less than 3 feet tall in a 7 gallon pot and has over 30 branches at this point. Every year it throws off many infos but not very many leaves. Typically a year's growth off any branch is under an inch.
I can't quite figure out what I have here, but I have to say I love the short low mound of flowers that it gives me every year.
