Alpine aster is a tough, low-growing perennial that produces cheerful daisy-like purple flowers in late spring to early summer, making it a classic choice for rock gardens and border edges. It prefers well-drained soil and performs best with a few hours of direct sun each day, though it tolerates partial shade. Once established it is easy to care for, requiring only occasional deadheading to encourage a tidy appearance.
