How can I grow a 15-20 foot plumeria / frangipani tree (not plant) in Houston, like the ones in Hawaii? ?

Question

I have plumeria plants about 3 feet tall it's just a stick with leaves, will these eventually turn into mature 15-20 foot trees like the ones in Hawaii or are my plant and tree two different things?

Answer 1

If you have it in the ground it will eventually grow bigger. If it's in a pot then you will have to keep getting bigger pots for it to continue growing. Prune during the winter (should be fall but no fall in Houston)
