Morning glories are annual climbers with slender stems, heart-shaped leaves, and trumpet-shaped flowers of pink, purple-blue, magenta, or white. They have beautifully-shaped blooms that unfurl in the sun and romantic tendrils that lend old-fashioned charm.
Train morning glories over a pergola or arch, or use as a dense groundcover. The vine grows quickly—up to 15 feet in one season—and can self-seed fairly easily, too. Therefore, choose where you put this plant wisely!
Note: Morning glory seeds are poisonous, especially in large quantities. Keep them out of reach of children and pets. Learn more.
Is it Morning Glory or Bindweed?
Annual morning glories (Ipomoea spp.) are often mistaken for their perennial cousin, field bindweed (Convolvulus arvensis), which is an aggressive, invasive weed native to Europe and Asia. Field bindweed—also called “perennial morning glory” or “creeping jenny”—grows similarly to annual morning glories, but sends out deep, deep roots, which make it very difficult to get rid of and allow it to overwinter in areas where cultivated morning glories could not.
To tell the difference between the plants, look at the leaves, flowers, and vines:
- Field bindweed leaves are typically smaller than those of annual morning glories. Morning glory leaves may be 2 inches or more across; bindweed leaves rarely exceed 2 inches. Bindweed leaves are also shaped more like an arrowhead than those of morning glories, which are heart shaped.
- Field bindweed flowers only occur in either pink or white, whereas annual morning glory flowers may be pink, white, magenta, blue, purple, or red, and are much larger than those of the bindweed.
- Morning glory vines are usually thicker than bindweed’s vines, and may have small hairs.
