Calico Aster

About Calico Aster

Calico Aster is named for the charming 'calico' effect created by its tiny white flowers, whose centers transition from bright yellow to a deep rosy-purple as they age. This unique perennial typically grows 2 to 3 feet tall, though it can occasionally reach up to 5 feet in ideal conditions. It is easily recognized by its distinctive horizontal branching habit, which gives it a layered, shrub-like appearance. Native to the open woods, thickets, and meadows of Eastern and Central North America, it is a highly adaptable plant that thrives in full sun to partial shade. Its abundant blooms, appearing from August into October, attract a wide variety of small native bees and butterflies, and it serves as an important host plant for the Pearl Crescent butterfly. Calico Aster is well-suited for medium-wet to medium-dry soils and is remarkably easy to maintain in a garden setting. Its fine-textured foliage and interesting growth form make it a versatile choice for adding late-season interest and ecological value to woodland edges or mixed native borders.
