Moonflower is a tender perennial vine that is winter hardy to USDA Zones 10-12. In St.Louis, it is grown as an annual in moist, well-drained soils in full sun. This vine needs a support structure upon which to grow. It is easily grown from seed. Start seed indoors about 6-8 weeks before last spring frost date. Notch seed coat with a knife before planting to promote better germination. Seed could be started outdoors after last frost date, but the onset of bloom would occur unacceptably late in summer. Take new young plants outdoors about 1-2 weeks after last spring frost date. Once established, growth is rapid. Seeds may be harvested in fall, but only mature seeds that have fully ripened on the vine are of value. Plants grown in containers could be brought inside in fall for overwintering, albeit with some difficulty, but most gardeners simply start new seed indoors each spring.
