Alpine aster is a low-growing native wildflower that forms compact mounds of small leaves topped with daisy-like purple flowers from July through September. This drought-tolerant perennial thrives in full sun and requires minimal watering once established. Its neat, compact growth habit makes it suitable for rock gardens, borders, and xeriscaping.
