big-leaf aster

Eurybia macrophylla (big-leaf aster) has large heart-shaped basal leaves forming a woodland groundcover in spring. 

In summer their stems emerge so that in early fall flat-topped clusters of purple to light blue ray flowers with yellow centers rise three or four feet above the forest floor. This aster flowers best in part sun, although its leaves will dry up and fade faster if it bakes in direct afternoon light.
