It is always good to experiment and see the results. And we do have a Plumeria forum too:
The thread "Chats About Plumeria" in
Plumeria forum
The plumeria bug bit me in 2009 when a friend of mine gifted me a cutting that bloomed on the same year. To increase my collection I started growing them from seeds. It took some years to bloom but they were worth the wait and I quickly ran out of space.
some members in the plumeria were successful in making their seedgrown plumeria bloom in less than 2 years.
