Plumeria plants which known as Lei flowers and Frangipani are native to tropical regions. The flowers of these plants are used in making traditional Hawaiian leis. They are fragrant and bloom freely from spring throughout fall in multiple colors.
Plumeria is a genus of flowering plants in the dogbane family, Apocynaceae. Most species are deciduous shrubs or small trees. The species variously are indigenous 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 also is used directly as a common name, especially in horticultural circles.
