Oxeye Daisy (Leucanthemum vulgare)

Quick Identification

Large blooms with white petals surrounding a yellow center
Generally reaches a height of 20 to 80 cm
Features wavy leaves that wrap around the stem
Produces black, ribbed seeds

Impact
This species outcompetes native plants and reduces forage for livestock and wildlife.

Management
Oxeye Daisies are often sold in wildflower mixes or through nurseries, so public education and awareness are crucial in controlling the spread of this species. Hand pulling or digging before seed production is an effective control method. Repeated mowing can prevent seed production, but may also stimulate re-sprouting. Herbicide treatments are also effective. Biocontrol is also being investigated as a potential control method.

Flowers
Flower heads have yellow centers and 20–30 white, petal-looking ray florets. The flowerhead is 2.5–5 cm in diameter.

Leaves & Stems
Lower leaves are lance-shaped with toothed edges and long petioles. Upper leaves are smaller, narrow, stalkless, and alternately arranged with wavy margins. Unbranched stems can reach up to 1 meter in height. They are smooth, often grooved, and are typically hairless.

Reproduction & Dispersal
Reproduces by seed and underground rhizomes.

Seeds

The seeds typically brown to black, and are small, achene-like, measuring around 1/16 inch long. A single plant can produce up to 26,000 seeds that can survive in the soil for a few years.

Roots
Has shallow, fibrous roots and short rhizomes that help anchor soil effectively.

Preferred Habitat
Thrives in a variety of environmental conditions and can grow well even in nutrient-poor soils. This plant is capable of maturing, flowering, and producing seeds at high elevations—up to 1000 meters (or 3000 feet). While it prefers full sunlight, it can also tolerate partial shade, and even light frost

Interesting Facts
