Shasta Snow Cap
Leucanthemum x superbum, commonly called Shasta daisy, is a hybrid developed by Luther Burbank (1849-1926) in the 1890s near snow covered Mt. Shasta in northern California. Burbank crossed Leucanthemum vulgare (European oxeye daisy), Leucanthemum maximum (Pyrenees chrysanthemum), Leucanthemum lacustre (Portuguese field daisy) and Nipponanthemum nipponicum (Japanese field daisy) to produce Leucanthemum x superbum which was given the common name of Shasta daisy. This hybrid typically grows to 2-3' tall with a spread to 18" wide. Leucanthemums were formerly included in the genus Chrysanthemum.Genus name comes from the Greek leukos meaning white and anthemum meaning flower in reference to the white flowers of some species.Specific epithet means superb.'Snowcap' is a compact Shasta daisy cultivar that grows to 15-18" tall with a spread to 12" wide. Large, single daisies (to 4" diameter) bloom profusely throughout summer (July to September) on stiff flowering stems rising above a medium to dark green basal rosette of narrow, coarsely-toothed, short-petioled, oblanceolate leaves (to 12" long). Each flower has bright white rays surrounding a bright golden yellow center disk. Narrow, coarsely-toothed, much shorter, sessile stem leaves are lanceolate. 'Snowcap' was introduced by Alan Bloom of Blooms of Bressingham in the 1980s.
