Known to tourists as the Hawaiian lei flower, frangipani (Plumeria rubra) is native to warm tropical areas of the Pacific Islands, Caribbean, South America and Mexico. These beautiful flowers -- which grow in shades of pink, red, yellow and white -- appear to be kissed with a touch of gold at the center. Frangipani has a distinctly tropical scent that grows more intense in the evenings, and the blossoms make a lovely addition to a dramatic bouquet.
Frangipani flower plants can grow to be large shrubs or small trees, with long leathery, fleshy leaves near the tips of the branches. Their flowers contain a poisonous, milky sap that can irritate the skin. In addition, the tree's wood can be used to make musical instruments, tableware, and furniture [source: The Flower Expert].
