Plumeria () is a genus of flowering plants in the family Apocynaceae. Most species are deciduous shrubs or small trees. The species variously are endemic to Mexico, Central America and the Caribbean, and as far south as Brazil and north as Florida, but are grown as cosmopolitan ornamentals in warm regions. Common names for plants in the genus vary widely according to region, variety, and whim, but frangipani or variations on that theme are the most common. Plumeria is also used as a common name, especially in horticultural circles. Description Plumeria flowers are most fragrant at night in order to lure sphinx moths to pollinate them. The flowers yield no nectar, however, and simply trick their pollinators. The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar. Insects or human pollination can help create new varieties of plumeria. Plumeria trees from cross pollinated seeds may show characteristics of the mother tree or their flowers might just have a totally new look. Plumeria species may be propagated easily by cutting stem tips in spring.
