Smooth Aster

Keystone Species. Long-lived perennial features striking sky-blue flowers in large, pyramidal clusters that bloom from late summer into early fall atop sturdy, upright stems. Its smooth, bluish-green leaves clasp the stems and help distinguish it from other asters, while also adding attractive foliage throughout the season. Thriving in full sun and a wide range of soil conditions, it’s a reliable, low-maintenance plant that supports pollinators and benefits from occasional trimming to encourage fuller growth and more blooms.
