Leucanthemum × superbum 'Snowcap'
A compact Shasta daisy valued for tidy mounds and abundant summer bloom. Plants usually reach about 12 to 18 inches tall with white single daisies. Its short stature helps flowers stand up to rain and wind better than taller forms. It thrives in full sun and well drained soils across much of North America. Deadheading helps keep new buds coming through summer.
