Identification and Reproduction

Identification

• Cypress spurge is an erect, tufted perennial, growing up to 30 cm tall in small to large patches. 
• Small, linear leaves in whorl pattern. 
• Yellow flowers grow in bunches. Flowers turn purple-red when mature.
• Yellow-green bracts under flowers. 
• Plants have a milky sap.

Reproduction

Reproduces vegetatively through lateral root shoots or seeds.

Habitat & Ecology

Cypress spurge typically is found in dry areas; pastures, meadows, streambanks, forest edges and distrubed sites. 

Impacts

Social:

• Reduce forage availability for livestock.
• May be toxic to animals.
• Milky sap may cause skin irritation.

Ecological

• Displaces native vegetation, degrading wildlife habitat. 

Management

Mechanical/Manual Control:

• Mowing (before seeding).
• Hand pulling will be effective for small patches. Be sure to wear gloves to prevent skin exposure to the milky sap. 

Chemical Control:

• Herbicide at early bud.
• May need to do repeat herbicide applications.
