Calico Aster features whitish, purplish rays with centers that mature from yellowish to reddish.  Sometimes the different-colored centers appear on the same plant.
 
Calico Aster easily grows in average, well-drained soils and prefers sun to partial shade.  It is clump forming and needs a little room to spread, but otherwise it makes a great garden plant.
 
Note: Pinching back the stems in spring will encourage branching and a denser look with more flowers.
