Smooth blue aster is a native North American perennial that delivers masses of lavender-blue daisy-like flowers from late summer through autumn, providing vital late-season nectar for pollinators. It thrives in average to well-drained soils in full sun to partial shade and tolerates a range of conditions once established. Cut stems back in late winter and divide clumps every few years to keep plants vigorous and floriferous.
