Oxeye Daisy

Species
Leucanthemum vulgare

Oxeye daisy (Leucanthemum vulgare) is a short-lived perennial that decreases forage for wildlife, decreases local plant biodiversity, and may compromise vegetative ground cover due to its growth form that results in exposed soil.

Considered regionally noxious under the BC Weed Control Act, oxeye daisy is of major concern in the Cariboo, Okanagan, Peace River, Thompson, and Omineca. It occurs at low- to mid-elevations in grasslands and dry to moist forests, and is present in the Kootenays, Lower Mainland, and Vancouver Island.

Oxeye daisy has daisy-like flowers at the end of course, slender stems, with lower spoon-shaped leaves. Central yellow disks grow 10-20 milimeters wide and white ray flowers 1-2 centimetres long. The plant can grow up to 1 metre in height at maturity. Oxeye daisy is often confused with the ornamental Shasta daisy, which has larger yellow disk (2-3 cm) and white ray flowers (2-3 cm).

Oxeye daisy reproduces by seed and underground stems. A single plant produces 26,000 seeds and dispersal from parent plants lead to nearby infestations. Due to its unpleasant taste, most grazers avoid this plant, leaving it to spread easily within grazed grasslands, pastures, and rangelands.

A few native and ornamental alternatives to plant instead of oxeye daisy include: White Swan Coneflower; White New York Aster; Cutleaf Daisy; Alpine Aster; and Beach Fleabane Daisy. Read more about these alternatives in the Grow Me Instead booklet for BC.
