Antigonon leptopus

About

Antigonon leptopus is a species of perennial vine in the buckwheat family commonly known as coral vine or queen's wreath. This clambering vine is characterized by showy, usually pink flowers that can bloom throughout the year and large, heart-shaped leaves. A. leptopus is native to the Pacific and Atlantic coastal plains of Mexico, but also occurs as a roadside weed from Mexico south to Central America. It is widely introduced and invasive throughout tropical regions of the world, including in the south and eastern United States, the West Indies, South America, and the Old World tropics of Asia and Africa. This species is utilized for its edible tubers and seeds, but also for its horticultural properties as an ornamental vine in warmer parts of the world.
