This is a classic example of a daisy. There are many white daisies that have been introduced from Eurasia as ornamental and herbal plants, although the Ox-Eye Daisy has larger flowerheads (more than 1¼' across). The various cultivars of Leucanthemum x superbum (Shasta Daisy) can closely resemble Ox-Eye Daisy in general appearance. The Shasta Daisy was developed by Luther Burbank from Eurasian species. Its flowerheads tend to be larger than those of the Oxeye Daisy (more than 2' across) and its leaves are less likely to be pinnatifid. In the Shasta Daisy, there is a brown membranous margin toward the apex of each floral bract, while the floral bracts of the Ox-Eye Daisy are brown along the entire length of their margins. Another scientific name for the Ox-Eye Daisy is Chrysanthemum leucanthemum.
