Noteworthy Characteristics:
Native to Europe, Aster sedifolius is a clump forming aster that features terminal sprays of 1.25?diameter asters (bluish-lilac rays with yellow centers) on generally weak stems rising 2-3?(less frequently to 4? tall. This species, sometimes commonly called Rhone aster, is infrequently sold in commerce because of the availability of the compact cultivar 慛anus? 慛anus?typically grows to only 18?tall and features flowers that are slightly smaller than the species with ray flowers that are a darker blue. Lance-shaped, medium green leaves (to 2.5?long). Blooms from late summer to early fall. Flowers are attractive to butterflies.
No serious insect or disease problems. Asters in general have some susceptibility to powdery mildew. Aster wilt can also be an occasional problem, particularly if plants are grown in poorly-drained clay soils. Taller plants may require staking or other support. Foliage tends to decline by late summer to early fall.
Uses:
Borders, cottage gardens or butterfly gardens.
