Like several annual warm season bedding plants, oxeye daisy, Leucanthemum vulgare, is actually perennial. Also, some of the less extensively bred sorts disperse enough seed to naturalize and potentially become invasive. Increasingly popular modern varieties that are prudent with seed might not be true to type. Some might revert to more prolific forms.

Modern varieties should not get much higher than a foot and a half. They should also be more dense than the simple species, which gets a few feet tall. Foliage and form is quite variable among varieties. Stems are solitary or branched. They may be leafy or sparsely foliated above basal rosettes. Leaves might be lobed or serrate, with or without petioles.

The solitary, paired or tripled composite blooms of oxeye daisy are not so variable. They are classic daisies, with a dozen to three dozen clear white ray florets surrounding bright yellow disc florets. Without deadheading, fresh new bloom overwhelms deteriorating old bloom. Oxeye daisy is splendid as a cut flower. Spring bloom continues through summer, and can actually continue sporadically for as long as the weather is warm.
