Moonflower (Ipomoea alba) is a nocturnal morning glory relative with large, pure-white, fragrant flowers that open in the evening and close by morning. The 5 to 6 inch blooms unfurl at dusk, scent the garden at night and glow in the moonlight, which makes it a classic for moon gardens and evening patios. A fast, twining vine that climbs 10 to 15 feet in one season, blooming from midsummer until frost. Grown as an annual outside zones 10 to 12; give it full sun and a trellis, fence or arbor. The seeds are toxic if eaten.
