Information on Moon Flowers

This morning glory looks much like the white moonflower.

If you enjoy spending time outdoors during summer evenings, you can brighten your yard with the pure white blooms of the moonflower. Related to the morning glory, this vine produces sweet-smelling flowers when the sun goes down.

Identification

The moonflower is an annual vine that comes from Central America. Botanically, it is known as Ipomoea alba, and belongs to the same genus as morning glories. This plant grows quickly and produces 12-foot vines within one growing season. Its flowers can reach 6 inches in diameter and only live for one night, later forming large seedpods.

Time Frame

You can grow moonflowers from seed purchased through catalogs or over the Internet. After your final spring frost, nick the outer seed shell to speed germination and then plant the seeds about 2 inches deep in fertile, well-drained soil. Make sure the location receives at least six hours of sunlight daily. Provide support for this rambling vine.

Potential

In spite of its lovely flowers, the U.S. Department of Agriculture has classified the moonflower as an invasive species in Arizona and Arkansas. In Arizona, it is a prohibited noxious weed; in Arkansas, it isn't prohibited, but it is listed as a noxious weed. Invasive species can take over an environment and create serious competition to native plants.
