Popular garden varieties of morning glory are descendants of various species of Ipomea. Too many species are involved to classify such varieties briefly. Perennial morning glory, particularly the blue dawn flower, can be invasive. Most others perform as annuals, so do not grow long enough to be invasive. However, they can self sow to become numerous.

Although it might self sow and grow in any soil, morning glory prefers rich and loose soil. It also prefers regular irrigation, and will wilt if its soil gets too dry. Roots disperse deeply, so dislike pots. Morning glory in pots typically stays smaller than the same in the ground. Morning glory grows best from seed, which should go into its garden at the end of winter.

Some annual varieties of morning glory can climb ten feet high. Some grow only four feet high. They are delightful on picket fences. Their cordate or lobed leaves are about two or three inches wide. Their simple circular flowers are about the same width. They bloom in rich hues of blue, purple, red, pink and white. Some types have stripes, streaks or spots. Several exhibit central star patterns.
