(Hardy Aster) Aster 'Celeste' is a new Yoder selection with dark green, disease resistant foliage on mounded plants with a compact habit. It is perfect for the front of the perennial border or mixed containers. In late summer through fall, the plants are completely covered with eye catching lavender blue single flowers with an attrative yellow eye. 'Celeste' looks stunning when planted with fall blooming ornamental grasses!
