Our June Weed of the Month is Ox-eye daisy (Leucanthemum vulgare) . Originally from Europe, ox-eye daisy was introduced to North America as a garden ornamental species. It is perennial and usually flowers between late May/early June into the fall. Being a member of the aster family (Asteraceae), Ox-eye daisies are composite flowers, with their ray florets being white and their central disc florets being yellow. The leaves are irregularly lobed and have serrated margins.This species is known to grow in sunny, open grasslands and disturbed areas such as roadways, railways, forest clear cuts, and riparian areas.

Removing ox-eye daisy can be somewhat arduous. This species is rhizomatous and has been observed to grow from root fragments. Manual removal is best in the early spring before the plant grows a flowering stem. The irregular leaves help to identify this plant without the flowers. For larger infestations, herbicide may be necessary.
