Smooth Blue Aster, Aster laevis
One of the most attractive blue asters, Symphyotrichum laeve (Smooth Blue Aster) is a clump-forming perennial boasting usually unbranched stems topped with profuse clusters of daisy-like flowers in late summer and fall. Blooming for weeks, the flowers, usually less than 1 in. across (2.5 cm), feature golden-yellow centers surrounded by rich lavender-blue rays. They are pollinated by insects, commonly attracting butterflies, bees, flies, and beetles. Borne on sturdy stems, their gentle color blends with almost any other color in the garden. They are pollinated by many native bees and attracts butterflies. The foliage of blue-green leaves is very smooth to the touch and handsome all season. Adaptable, Smooth Blue Aster is an excellent choice for the perennial border where it makes a beautiful foil for other late-season perennials. Equally handsome in natural landscapes and prairie restorations.
