Ipomoea alba

Ipomoea alba, commonly called moonflower or moonvine, is a night-blooming morning glory in the family Convolvulaceae, native to tropical and subtropical parts of the Americas from Argentina north through Mexico, Arizona, Florida and the West Indies. It is a perennial herbaceous liana that climbs 5 to 30 meters, with entire or three-lobed leaves 5 to 15 centimeters long. Its fragrant white or pink flowers, 8 to 14 centimeters across, open rapidly at dusk and stay open through the night until touched by morning moisture. The nearly spherical yellowish-brown to black seeds are buoyant and can float for extended periods, but all parts of the plant, including leaves, flowers and seeds, are toxic to humans and animals.
