Plumeria flower with blue sky

Plumeria is related to the Oleander, Nerium oleander, and both possess an irritant, rather similar to that ofEuphorbia. Contact with the sap may irritate eyes and skin. Each of the separate species of Plumeria bears differently shaped alternate leaves with distinct form and growth habits. The leaves of P. alba are quite narrow and corrugated, whereas leaves of P. pudica have an elongated shape and glossy, dark-green color. P. pudica is one of the everblooming types with non-deciduous, evergreen leaves. Another species that retains leaves and flowers in winter is P. obtusa; though its common name is "Singapore," it is originally fromColombia.
