- Description

Moonflower is a tender, low-maintenance, perennial vine grown as an annual in North Carolina. It gets its common names from its fragrant, nocturnal, white flowers, which open rapidly over the course of a few minutes. It is a member of the morning glory family (Convolvulaceae). The species epithet is Latin for "white."
Plant in locations with well-draining clay, loam, or sandy soil that receive full sun. Moonflower can grow to 15 feet in height and 3 to 6 feet in width. The vines will grow slowly until the weather becomes very warm, at which time their growth rate becomes rapid. Propagate by seeds. Start 4 to 6 weeks before the last spring frost by soaking seeds overnight in warm water or nick with a file to break the seed coat.
Since Moonflower is a vertical climbing vine, it needs a support structure like a fence, arbor, or trellis to grow. The plant has 8-inch, heart-shaped leaves and large white trumpet-shaped flowers that open at night and provide a sweet fragrance. Plant it in a cottage, patio, night-time, or pollinator garden where you can fully enjoy the beauty and scent of the showy white flowers while you watch the aerial show of moths as they pollinate the blooms. It is a host plant for the Hummingbird moth (Macroglossum stellatarum) as well as Sphinx moth (sphingidae). If you would like to overwinter the plant, then grow it in a large container and bring it indoors over the winter.
Insects, Diseases, and Other Plant Problems: No significant problems.
