The moonflower (Ipomoea alba), a perennial tropical native, is grown as an annual in northern regions. This high-climbing relative of the morning glory blooms by the light of the moon and emits a heavenly scent. Pollinated by moths, the moonflower plant can grow up to 15 feet high and produces wide, delicate blooms in pale shades of white and pink. Easily propagated by harvesting the seeds, the lush foliage and romantic blossoms of the moonflower will bring beauty to any trellis or fence for years to come.
Allow the moonflower to bloom. Blooms open in late afternoon and bloom throughout the evening. They are produced sporadically throughout the growing season.
Remove the seedpod from the faded bloom, either after the flower dies off or once the pod has dried on the stem.
Allow the seedpod to dry completely, then gently cut it open to remove the moonflower seeds.
Store moonflower seeds in an airtight plastic storage bag once they have dried. Keep seeds in a cool, dry location without direct light until ready to plant.
