In March 2014 I ordered a cutting of P.obtusa. It came and was a nice 14-15" hunk. I planted in potting soils with 60% perlite. But being it was still March I felt like it needed some help even indoors..so I bought a heating mat to put under the cutting. As of mid April,I see new leaves juuuuust moving. I will update as I often try to do on DG.
btw,Whats said about the plant that I hope is true, is that Plumeria obtusa is a much better potted Plumeria plant then P.rubra. We will see.

ADDED: Its now mid June of 2014,and its still unfolding...the stem has rooted as the plant has filled in the wrinkles it developed as a bare cutting. Glossy stem tip. Pretty much even with a Royal Hawaiian P.rubra cutting started at the exact same day. Both are outside in pots in full s... read more

Plumeria obtusa is native to much of the Caribbean and sometimes also listed as native to parts of extreme South Florida (Monroe and Collier counties), although in general it is considered naturalized here.

Like P. pudica, P. obtusa is evergreen in South Florida and looks nice all year round. The white flowers are very fragrant and trees regularly set seed. Plants are very easy to care for if kept in well draining soil, and generally do not benefit from any supplemental water here. Plumerias planted in swales or in moist areas fail to thrive and are prone to rot.

Bought it at Home Depot about four years ago. In full sun with southern exposure. In bloom most of the year.
Use good grade time release palm fertilizer three times
a year, soaker hose. Very lush; will probably trim in back
a litte and use trimmed branches to try to start new plants.
We live in south Miami Dade County, Florida

This plumeria actually does well in zone 10a in southern California, and I have had one in zone 9b for 5 years with minimal (but always some) cold damage. I personally have found this species is actually MORE cold tolerant than the more commonly planted P rubra. It does sort of become deciduous at this extreme of its climate range, and it prone to rot if you're not careful... slower grower than P rubra, the more common species out here in So Cal. Flowering is far less frequent, as well. This plant tends to do well for very long time kept in a pot, which is not necessarily the case with most Plumeria rubra varieties.

You can tell if from P rubra in that it is NOT deciduous (normally) and the leaves are more deeply divided with prominent veins that run nearly perpendicular... read more

The Singapore Plumeria, Plumeria obtusa, is evergreen though it is a little less cold tolerant than other plumerias. Flowers come only in white with a little yellow center. Much more fragrant that other plumeria varieties. It is my favorite plumeria.
