Hey disney.

It can be very confusing for sure.
the genus is 'Plumeria'

the most common species you will see posted here are "Obtusa" and "Rubra". I dont know if anyone here grows the species "Pudica" but they are nice also. thinner leaves and smaller flowers then the other 2. there are a couple other species but I dont believe they are very common.

Singapore is the name of the most common obtusa species. There are other names of obtusa such as "dwarf singapore pink.

by far the most common you will see posted here and are the most varied are different cultivars of the rubra species. But hang on it can get even more confusing now. There are quite a lot of registered cultivars but there are also many that have several names. for example "confetti" is also known to some as "barbados showgirl"

As far as cross grafting I really dont have an answer.

Also I am still very new to plumeria and there are many, many other members here whose knowledge far out weighs mine so hang someone will be by shortly to help answer your questions.

I attached the link to the plumeria society page if you are interested. they have a list of their officially registered names.

Rubra is a species and Obtusa is a species - Singapore is the common name of the Obtusa species and there are a few variations of them like Dwarf Singapore Pink, etc.. Chances are, the one you mentioned, Kulap Waeng Ping Rose is the name of a particular plant in the Rubra species, although I am not familiar with it to say for sure. You will see many names like Celadine, Penang Peach, Scott Pratt, etc. and they are all varieties of Rubra.

Rubra is the type that are deciduous (lose their leaves / go dormant in winter) and you will notice them more often as they are typically the colorful ones, although there are many white Rubra flowers as well. Obtusa are evergreens and require slightly different growing conditions than the Rubra varieties, and the Obtusa are known for their strong fragrance.

One of the biggest differences will be in the appearance of the leaves - the Obtusa are very shiny and oblong.

I hope this helps! Keep reading up on it and looking at pictures and it will start to make sense. Happy growing and please keep us updated on your progress!

Hey Mike, great info, we must have been posting at the same time LOL!

Hey E

thanks, you too!

Mike

I see. Chances are all of mine are rubra then... Which is a good thing! I just realized that there was more than "just plumeria"...
