Plant Morning Glory seeds in a hanging basket and they will grow down! Morning glory seeds are protected by a tough coat. Soak the seeds in water for 12 to 24 hours before sowing or file away or nick off a small piece of the coat before planting.
Gather multiple potted plants to create the splendor of an in-ground border in a spot where gardening is otherwise impossible. Using containers, you can fill a space with beautiful color and texture that rivals earthbound planting beds. - My Cool Garden
