Which flowering tree genus is commonly grown as ornamentals in warm regions, Plumeria or Vitex?
Plumeria 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 circles.
