Aster 'Purple Dome' is a compact, mounding perennial known for its vibrant purple blooms and tidy growth habit. Reaching about 18 to 24 inches tall and wide, it produces masses of daisy-like flowers with yellow centers in late summer to fall, attracting bees and butterflies. Its dense form and rich color make it perfect for borders, rock gardens, or pollinator-friendly plantings. 'Purple Dome' also provides valuable late-season color when many other perennials are fading.

To grow Aster 'Purple Dome' successfully, choose a location with full sun and well-drained soil. While it tolerates a range of soil types, it performs best in moderately fertile, moist soil. Avoid overhead watering to reduce the risk of powdery mildew, a common issue with asters. Regular deadheading encourages prolonged blooming, and cutting back stems by one-third in early summer can promote bushier growth. Divide every 2–3 years in spring to maintain plant health and vigor.
