Smooth Blue Aster is a hard-working wildflower with a wide native range across Eastern and Central North America. The long-lasting flowers feature soft blue petals that radiate from golden centers, which turn reddish later in the season. It is a butterfly magnet and a larval host for striking Pearl Crescent and Silvery Checkerspot butterflies. Happiest in a full-sun to part-sun spot and almost any soil type, Asters just need room to grow. This is an excellent choice for meadowscaping and natural garden design. Lovely lavender-blue flowers harmonize beautifully with Purple Coneflowers, Goldenrod, and Black Eyed Susans.
