Plumeria emarginata endemic to karstic areas in Northern Cuba has narrow leaves with very revolute margins.
It bears flowers profusely through the warmer months. It has been growing in the Canaries for decades and we still propagate the real thing. Some websites and botanists wrongly believe that Plumeria emarginata Griseb. is a synonym of Plumeria obtusa L. but believe us - This definitely NOT A PLUMERIA OBTUSA !
