The name "morning glory" comes from the fact the flowers open every morning. Plant seeds outdoors after all danger from frost has passed. Soak the seeds overnight before you plant them. The seed coats are very tough. Plant in full sun. Plant the seeds 1/2 inch deep. Space the seeds twelve inches apart. Morning glories will grow to ten feet tall. They will need some kind of support (trellis) to grow on. They will grow up a chain link fence, but not a wall.
