|Offering masses of daisy-like blooms, use plants from this large, diverse group for formal borders, and rock and natural gardens. The low-growing Alpine Aster blooms in spring. More common types are hybrids of New York Aster, which bloom in late summer and fall when many perennials are finished. Best in full sun, but partial shade in hot southern climates. Feed sparingly to avoid lush growth susceptible to mildew and diseases. All Aster frikartii varieties are somewhat resistant to mildew. Plant in well-drained soil to avoid root rot. For bushier plants with more flowers where growing season is long, pinch back in spring when shoots are 6 inches and later in early summer. Divide plants at least every other year before flowering decreases and inner shoots of clumps lose vigor. Replant only healthy outer divisions.
Stiking, clear lavender-blue flowers and a well-branched, elegant form make this one of the finest perennial Asters. Use with silver-leafed plants such as Artemisia 'Powis Castle'. In areas with mild winters, produces some flowers throughout the year if dead blooms are removed.
