Michaelmas daisies are regarded by some gardeners as plants which can be left to look after themselves, bearing pink or lavender flowers each autumn on 3 ft stems. Such views are either wrong or incomplete. The Aster is certainly not a trouble free plant, powdery mildew and other diseases can be a serious problem and the staking of tall varieties will be necessary. The flower heads of this cultivar are snowy white, an aster color with which you may not be familiar. White flowers flawlessly integrate a variety of pastel shades and can also soften the intensity of bold-color blooms.
A. alpinus thrives in full sun with average to poor, well-draining soil. Bloom time is from late spring to early summer, and sometimes mid-summer. Mature dimensions average 8 to 12 inches tall and wide.
