Thank you all for your kind responses to my pics. It's as I thought, I may never know for sure, the names of all the Plumerias I own, and I will just have to live with it! I have however created an inventory of my plants with bloom size, colors, leaf type, etc. so although I may never know, oh well! The purple flower was the one I was most enamored with, but that particular color lasted for only 3 days and then faded quickly. That was last year, and I have not seen this bloom since. I will check out your suggestion. Here in southern CA, it gets so hot, at over 100 degrees the plumies get sunburned and sometimes need water daily, so I spend a lot of time making sure everyone stays healthy and white-fly (Plumeria nemesis)free. More of my beauties attached. These I know! In order: Captivate, Dragon Tears, and Electric. Happy Sunday to you all.
