This is one of a group of closely related white, narrow-leaved asters that presumably interbreed and are difficult to distinguish. The common name refers to the fact that the heads are at first yellow and later turn purplish-red, so that flowers on one plant and even a single head may include both colors at the same time.

This aster grows up to 5' tall with profuse blooms in the Fall and serve as an important nectar source for migrating monarch butterflies and other pollinators. Calico Aster prefers full sun and can thrive in terrible soil.

Host plant for the larvae of the Pearl Crescent and Silvery Checkerspot butterflies, as well as other insects .
