Symphyotrichum laeve

Smooth Blue Aster (Symphyotrichum laeve) is a perennial wildflower native to fields, open woods, and roadsides. It typically grows up to 4 feet tall and features smooth, blue-green foliage with clusters of lavender-blue flowers that bloom from late summer into fall. This aster thrives in full sun and prefers medium to dry, well-drained soils, making it tolerant of drought once established. Smooth Blue Aster is well-suited for prairie gardens and naturalized areas, attracting pollinators such as bees and butterflies. It requires minimal watering after establishment and is adaptable to a range of soil types, though it performs best in soils with moderate fertility.
