Bougainvillea, a most beautiful flower

Bougainvillea is a genus of thorny ornamental vines, bushes, and trees with flower-like spring leaves near its flowers.
The vine species grow anywhere from 3 to 40 ft. tall, scrambling over other plants with their spiky thorns. The thorns are tipped with a black, waxy substance. They are evergreen where rainfall occurs all year, or deciduous if there is a dry season. The actual flower of the plant is small and generally white, but each cluster of three flowers is surrounded by three or six bracts with the bright colors associated with the plant, including pink, magenta, purple, red, orange, white, or yellow.
