It is also a self-seeder, so if you don't want it to return next year, pick off the spent flowers so they don't form seed pods. Also, these are huge and vigorous vines that can grow 8-10 feet, so will need a large trellis.
Producing large, spectacular white flowers as the sun goes down, or sometimes on cloudy days, moonflowers are perfect to grow in an outdoor eating area, or near a bedroom window, where their fragrance can sweeten the night air.
Moonflowers have large, beautiful, heart-shaped leaves that grow on vigorous vines, reaching eight feet or higher. The flowers are huge, around six inches long and three to six inches at the widest part. Iridescent white, the flowers are trumpet shaped and spectacular.
Grow moonflowers with morning glories for spectacular display all day and night.
