Leucanthemum vulgare

Leucanthemum vulgare, known in English as "ox-eye daisy", "moon daisy", "dog daisy", or "marguerite", and in French as marguerite commune, is a perennial native to Eurasia and widely escaped in North America, Australia, and New Zealand.

Ox-eye daisy is difficult to eradicate once established, since it can regrow from root fragments left in the soil. Better to not let it get established, or keep it in a container and deadhead religiously.
