Asters attract butterflies
Aster thrives in areas with cool, moist summers. It produces blue, white, or pink flowers in the late summer or fall. Plant height ranges from 8 inches to 8 feet, depending on variety. Tall varieties make good back-of-the-border plants and are also attractive planted in naturalized meadows. Aster is susceptible to powdery mildew and rust diseases, so choose disease-resistant varieties.
