Bougainvillea

Bougainvillea (also known as Napoleón, veranera, trinitaria, Santa Rita or papelillo) is a genus of flowering plants native to South America from Brazil west to Perú and south to southern Argentina. Different authors accept between four and 18 species in the genus. They are thorny, woody vines growing anywhere from 1 to 12 metres tall, scrambling over other plants with their spiky thorns. The thorns are tipped with a black, waxy substance.
