Ipomoea purpurea
Common morning-glory is an annual deciduous vine with alternating heart-shaped leaves and large, purple flowers that may show streaks of white and pink. The two inch flowers, which open in the morning and only last a few hours, are prominent from July to September. The vine, which is covered with fine hairs, may grow between ten and sixteen feet in height by twining around other structures.
Common morning-glory can be found along roadsides, planting fields, thickets, and waste areas. Because it prefers sunlight, the common morning-glory tends to grow in places with high exposure. It grows throughout the United States, except in Alaska, Washington, Oregon, Idaho, Montana, Wyoming, and Colorado.
