BINDWEED is a plant with long string like stems that twist and grow over other plants. Three bindweeds grow in the United States. They are pests to farmers because they make harvesting of crops difficult. Their many leaves shut out the sunlight from the plants used to make food, causing them to starve to death.
The worst of the bindweeds is the European bindweed, sometimes called small-flowered morning-glory. It has white or pinkish flowers less than an inch long. Its trailing stems are as long as ten feet. Its roots go deep into the ground, sometimes more than 15 feet. It is a perennial and so comes up year after year. Its flowers measure 1.5 to 3 inches 13.8 to 7.6 centimeters) long.
