How to Grow Morning Glories & Moonflowers Together

Morning glory (Ipomoea purpurea) and moonflower (Ipomoea alba) are closely related annual vines that when grown together offer blooms around the clock. Moonflowers' large white blooms open in the evening after sunset, attracting night moths to the fragrance of the flowers. Morning glories' fragrant colorful blooms open early in the day and remain open until sunset. Structures such as new fences give the vines something to twirl around as they grow. Keep a close eye on the vines if you plant them along with other ornamental plants and shrubs, as they can quickly engulf other plants.

Instructions

- 1
  Pick a location that offers full sun or light shade to plant your morning glories and moonflowers. The location you choose must drain well after watering or a rain.
- 2
  Provide the flowing vines something to which they may attach themselves as they grow. Install a trellis or attach wires to a wall next to the planting location.
- 3
  Nick each seed lightly with a metal file to break through the seed coat. Place the seed in warm water to soak overnight.
- 4
  Plant the seeds outdoors when ground temperatures are between 65 degrees and 85 degrees Fahrenheit. Push the seeds about 1/2 inch beneath the soil next to the trellis or wall. Keep the ground moist until the vines emerge, which should occur in about four to seven days.
