These annual weeds have twining, hairy stems that grow 2 to 20 feet long. The heart-shaped, hairy leaves are 2 to 6 inches long. Trumpet-shape white, purple, red, or blue flowers bloom from July to October. Seeds are formed within bristly pods that adhere to clothing or animal fur and are carried to other areas. The seeds lie dormant in the soil over the winter and germinate in the spring. Morning glories may sprout anywhere in the yard and frequently creep into yards from neighboring areas. They tolerate any type of soil but are most troublesome in sandy soil.
In a frequently mowed lawn, morning glory should not be a problem. In the garden, young plants can be hand-pulled, hoed, or controlled with a deep mulch.
