'Bluebird' Smooth Aster has lots of showy bluish violet flowers in late summer and early fall over clean foliage. 'Bluebird' is a great introduction from the Mt. Cuba Center in Delaware. Ranked as the #1 Aster in an evaluation study at Mt. Cuba Center. Strong stems do not need staking if cutback somewhat in June. Carl Hesselein's favorite Aster for flower color, disease-free foliage and upright stature in the garden. (New name is Symphyotricum laeve.)
PRN Preferred: Tons of flowers with no staking required. Winner!
