The morning glory (Ipomoea tricolor) is an ornamental vine related to the sweet potato. It's prized for its hardy nature and bright flowers. Though gardeners typically start morning glories from rooted cuttings, their seeds also can be sowed. Plant the seeds directly in the ground, as the plants don't do well with disturbed roots and may not survive transplanting from a pot, according to Washington State University.
Rub the morning glory seeds with fine sandpaper until the seed's surface appears rough and scratched to help water penetrate the hard seed coat that otherwise repels water.
Soak the seeds in a container of water for 24 hours.
Prepare a gardening site that has well-drained soil in full sun. Break up the soil with a spade to a depth of 8 to 12 inches. Mix in 3 to 4 inches of compost to condition the soil and improve drainage.
Plant the morning glory seeds. Bury two seeds at each spot, sinking the seed 1/2 of an inch below the soil surface. Separate the seeds by 5 inches.
Water the planting twice twice daily to keep the area consistently moist. Pull out one of the two seedlings, leaving behind the tallest and strongest one after the seedlings are 4 to 6 inches tall.
