(taken just above my head at the swimming pool) 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, Polynesia, Central America, and the Caribbean, and as far south as Brazil, 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 circle. 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. The genus is named in honor of the seventeenth-century French botanist Charles Plumier, who traveled to the New World documenting many plant and animal species. The common name "frangipani" comes from a sixteenth-century marquis of the noble family in Italy who claimed to invent a plumeria-scented perfume,.
