Ipomoea alba—commonly referred to as Moonflower Vine, Moon Vine, and Tropical Flower Morning Glory Vine—is a tropical, perennial vine that's known for its nocturnal flowering and attractive fragrance. 

Moonflower Vine is a fast grower, especially in hot weather! Expect at least 10' of growth, with some growing over 15' tall.

Moonflower produces new flowers on an almost daily basis from midsummer through early fall. 

Virtually disease and pest free! 

It's great at climbing all types of things such as trellises, houses, fences, and trees.

Ipomoea alba will form seeds in early fall, which can be harvested for planting next year. 


Moonflower Care

Ipomoea alba is typically grown as an outdoor plant, although it's sometimes grown as an indoor annual or a patio plant. 

Does best and grows fastest in humid conditions when the temperatures are above 80°F. Do not plant when soil temperatures are below 55°F. 

Moonflower loves full sun, and also thrives in partial shade. 

Keep its soil moist, but not wet. Irrigate during establishment, and during periods of drought. 

Fertilize as required, especially if planted in poor soil. It's best to fertilize Moonflower Vine with 1/2 strength fertilizer, as it's a light feeder.  Our slow release plant food or something similiar is a good option. 

This is not a frost tolerant plant.
