- Description
-
The calico aster is a bushy herbaceous perennial in the daisy family (Asteraceae) native to central and eastern North America from Canada to Mexico. It is typically found in moist meadows, woodlands, and near rivers, and swamps.
It grows about 1 to 4 feet tall and 2 to 3 feet wide and prefers light shade and moist conditions in rich loamy or clay soils. They are tolerant of occasional flooding. Dry weather will cause the leaves to wither and cause plant stress.
Small showy white flowers appear in clusters and bloom in late summer and fall attracting butterflies and bees.
The Calico Aster is a good addition to a partially shaded cottage, woodland or pollinator garden.
Insects, Disease, and Other Plant Problems: There are no serious insect or disease problems. Observe for verticillium wilt, powdery mildew, and gray molds. Due to its growth habit, the plant may require some support.
