Although native to the American tropics, tall morning glory (Ipomoea purpurea, Convolvulaceae) has been spread throughout much of temperate North America by humans. Gardeners favor this plant for its big heart-shaped leaves, beautiful purple flowers, and its attractiveness to butterflies and hummingbirds.
As is often the case this introduced species has escaped cultivation and can now be found in the wild. It’s perhaps most commonly encountered near fields, roads, and other sunny disturbed areas where it easily establishes itself. Although attractive, it’s non-native, invasive nature has earned it noxious weed status in several states.
