This perennial plant grows up to three feet tall. An extensive root system, up to 20 feet long and more than 14 feet deep, with multiple shoot-producing buds, makes this plant very difficult to control.
The leaves are narrow, one to four inches long.
A native plant of Eurasia, leafy spurge is an aggressive invader of pastures, rangeland, stream banks, and waste areas. It reproduces by seed and rootstock. It is toxic to cattle and may result in their death.
In late spring, yellow-green flower bracts appear.
Stems exude a milky fluid when damaged.
Seeds are contained in a three-celled capsule, one seed per cell. When dry, capsules can shoot seeds up to 15 feet from parent plant.
