Plumeria (/pluːˈmɛriə/; common name plumeria) is a genus of flowering plants in the dogbane family, Apocynaceae. It contains primarily deciduous shrubs and small trees. The flowers are native to Central America, Mexico, the Caribbean, and South America as far south as Brazil but can be grown in tropical and sub-tropical regions.
Plumeria is related to the Oleander, Nerium oleander, and both possess an irritant, rather similar to that of Euphorbia. 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 from Colombia.
Plumeria flowers are most fragrant at night in order to lure sphinx moths to pollinate them. The flowers have no nectar, however, and simply dupe their pollinators. The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar.
In order to get the most from a plumeria plant with respect to growth, size, blooms, and scent, there is a fine balance that must be maintained. Ideally, a plumeria is in its element when it can have plenty of sun and appropriate water, so as to maintain soil moistness just above a state of dryness.
There are more than 3000 named plumeria and 400 registered varieties of Plumeria. Registered by The Plumeria Society of American, Inc.
