Winter hardy to USDA Zones 10-11 where it may be grown as a perennial. North of Zone 10, it is typically grown as an annual. Plants perform well in average, consistently moist but well-drained soils in full sun. Avoid wet soils. Plants dislike the hot and humid summers of the deep South. In St. Louis, purchase plants in cell packs from local nurseries in spring. Plants may also be grown from seed started indoors about 6-8 weeks prior to last spring frost date so plants will produce good bloom in advance of the onset of hot summer weather. In cool summer climates, seed may be sown outdoors in the ground around the last spring frost date. Cuttings may be taken in late summer for overwintering.
Native to South Africa, blue daisy (also known as blue marguerite) is a bushy, aster-like, woody-based subshrub that typically grows to 2’ tall. It is primarily grown for its long and showy bloom of daisy-like flowers (to 1.5” diameter) featuring sky blue rays and yellow centers. In cool northern summers, flowers bloom throughout summer into fall (sometimes to frost). In hot southern summers, flowering usually declines or stops by mid-summer as consistent high temperatures become the norm. Rough-hairy, ovate green leaves (to 1” long) resemble leaves in the genus Amellus (also native to South Africa), hence the specific epithet. Felicia amelloides is synonymous with and formerly known as Felicia aethiopica, Aster amelloides, Aster capensis and Aster coelestis.
No serious insect or disease problems. Aphids and spider mites can be troublesome. Root may occur, particularly in wet soils. Watch for botrytis.
