In my opinion, 'Celadine' is as good as it gets when it comes to rooting, growing, using as root-stock, flowering, and fragrance. Too many people new to plumeria growing, purchase hard-to-root plumeria cuttings and when they die, they think they did something wrong. 'Celadine' belongs in everyone's collection. I was told by a large grower/hybridizer on Maui that Celadine's fragrance is what all other plumerias' fragrances are judged by.
Again, this is just me talking, if someone doesn't have a lot of experience in rooting cuttings, and if he/she wants difficult-to-root plumeria, purchase those that are rooted. Pay a few dollars more for piece of mind. A dead plant, regardless of how little money was spent for it, is still money wasted.
