The moonflower vine (Ipomoea alba) is a relative of the morning glory vine. The difference is the moonflower vine produces blooms in the evening instead of the morning. The flowers of the moonflower vine are large, up to 5 inches across, and white. The flowers have a fragrance that attracts pollinating moths. Moonflower vines are grown as an annual in most parts of the United States and grow to 10 feet long on a trellis or rambling over shrubs. The seeds have a very hard protective coating, and some treatment before they are planted helps the seeds sprout faster.
Fill a glass or jar half full with warm water. The water temperature should be about the same temperature as the water would be if you were taking a hot bath.
Place the moonflower seeds in the glass of warm water. Some of the seeds will float and others will sink to the bottom. Do not stir the seeds or try to force them to the bottom of the glass.
Remove the seeds from the glass of water after 24 hours. They may be slightly soft to the touch, so do not squeeze them and damage the tender seedling inside the seed coating.
Plant the moonflower vine seeds 1 to 2 inches deep in moist garden soil enriched with a 1-inch layer of compost. Dig a hole with a handheld garden shovel before placing the seeds into the soil. Do not push the seeds into the soil because you may smash and damage them. Gently cover the seeds with moist garden soil and very lightly tamp down the soil over the seeds.
Moisten the soil regularly until the seeds begin to sprout in about 10 days. Continue keeping the soil moist as the plants grow. Do not allow the root systems to completely dry out during the growing season. Although moonflower vines are slightly drought tolerant, they produce better blooms if supplied with regular moisture.
