Plumeria [common name Frangipani] is a genus of flowering plants in the dogbane family, Apocynaceae. It contains seven or eight species of mainly deciduous shrubs and small trees. They are native to Central America, Mexico, the Caribbean, and South America as far south as Brazil but have been spread throughout the world’s tropics.
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.
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.
