If yours branched, chances are that it bloomed at some point or at least started to bloom and maybe aborted -- unless it was a seedling and nubbed. Cuttings can bloom while rooting if taken from a flowering tree, or they can bloom shortly after being rooted -- i.e., a season or two if all their needs are met.
Seedlings, on the other hand, can take years and years to bloom for the first time. I'm still waiting on some six-year-olds. I know someone that waited 20 years for a seedling to bloom. They say the average length of time is 3-5 years for a seedling.
There are some cultivars that will bloom every year no matter what. 'Celadine' is like that. The nursery probably has one that is a reliable bloomer.
Make sure your plumeria is getting full sun, plenty of water and fertilizer, and good drainage. After that, all you can do is wait. If you are getting impatient for blooms, call Carol at Florida Colors Nursery and ask her to send you a grafted plumeria that has an inflo on it. I'm sure she'll be glad to help you out.
Hi Imzadi, an inflo is an inflorescense -- i.e., flower stalk. A nub is what seedlings send out in place of a flower stalk when it is not ready to bloom yet. I still have six-year-old seedlings sending nubs out, and I'm in a fairly ideal zone for plumerias. That can be very frustrating and is the reason that I discourage seed sowing for the average grower. If you have the space -- one seedling takes up a tremendous amount of room eventually -- and the patience, then that is great.
I am leaving the seed sowing to people like Luc of Florida Colors Nursery and Kukiat in Thailand, both of whom have lots of land and patience to grow out seedlings. Remember that oftentimes thousands of seeds have to be sown to come up with a unique flower. Those hybridizers have the courage and the wisdom to destroy inferior trees when the seedlings produce flowers that are not worth saving.
i have the room a couple acres for them so not a biggy but just want to see them bloom. when i started this project i fell in love with them and could only find seeds. if i had known about cuttings back them i surely would of went that way if i knew they would bloom quicker. so guess i will look into cuttings. thanks
