Moonflower
Ipomoea alba, often known as Moonflower, is a perennial vine with huge white blooms that bloom after dusk and remain open until sunlight falls on their petals. On days when the sun is obscured by thick clouds, it has been known to stay open a little longer into the day.
Moonflower is distinguished by its heart-shaped leaves, vigorous vine, and huge white blooms that open fast, have a lovely aroma and bloom nightly from midsummer until fall.
Moonflower prefers warm, tropical climates and is native to Florida, Louisiana, Texas, Puerto Rico, and the Virgin Islands, where it grows best next to a trellis, fence, or other means of support. However, in milder climates, it is frequently grown as an annual bloom.
