'Bluebird' is a fantastic selection of the native Smooth Aster introduced by Dr. Richard Lighty of the Mt.Cuba Center. This tall vased-shaped wildflower has large 1" diameter blue flowers held in cloud-like clusters at the tips of the arching branches. You can pinch back the young shoots in June for denser habit and more flowers, but it is not essential. Staking is helpful by late summer if you forget to pinch. Perfectly clean foliage makes for easy maintenance. Aster laevis is a great source of nectar for migrating monarchs and other late season butterflies.
