• Lower leaves are spoon-shaped and toothed

• Upper leaves are narrow, toothed, and clasp the stem

• Yellow disc flowers and white ray flowers make up the flower head

• Flower heads are solitary on the end of stems

• Flowers June through August

• One plant typically produces over 2,000 seeds which may be viable for over 30 years

• Establishes readily on bare soil

Negative Impacts

• Wildlife habitat is severely degraded by the rapid spread of oxeye daisy

• Wildlife and cattle avoid grazing it which allows it to take over entire pasture and meadow landscapes

• Oxeye daisy’s shallow root system can lead to expedited erosion

Management Strategies

• Hand pulling can be effective on small populations if care is taken to remove the entire root and is done consistently for many years

• Grazing by goats or sheep can be effective control

• Chemical control can be effective control for oxeye daisy. For a list of suggested herbicide active ingredients for oxeye daisy control, please refer to the 2025 CSU Herbicide Recommendations
