An escaped ornamental, this low growing perennial plant is native to Eurasia. Leaves are very slender, linear and are about a half- to one-inch long. All parts of the plant contain a milky sap that is a skin and eye irritant. Gloves and eye protection should be worn when handling vegetation. Flowers are yellow-green and are in clusters at the end of the stems. The plant was used extensively as a ground cover in landscaped areas and is most commonly found near residential areas in moderately moist, sunny locations.

Cypress spurge is considered an A list species and is designated for eradication in Colorado. It has been found in Crystal Springs as well as in certain landscaping situations in Carbondale and Glenwood Springs.
