Short's Aster (Symphyotrichum shortii) Short's Aster is a tough, shade-tolerant native perennial with delicate pale lavender to blue flowers that bloom in early fall. Valued for its late-season nectar, it's a magnet for butterflies and native bees at a time when few other plants are blooming in the woodland understory. This aster thrives in part shade, making it a go-to for woodland edges, savannas, and shaded pollinator plantings. Key Characteristics Late-Season Pollinator SupportShort's Aster is a critical nectar source for monarchs during fall migration and supports a wide range of native bees, including specialist species like Andrena asteris that depend on asters for pollen. Host Plant for Butterfly LarvaeServes as a larval host plant for the Pearl Crescent (Phyciodes tharos) and several checkerspot species, contributing to the full life cycle support for these butterflies. Thrives in Shade and Woodland EdgesOne of the few asters that performs well in part shade to full shade, Short's Aster is ideal for adding late-season color and ecological function to oak-hickory understories, streambanks, and north-facing slopes. Low-Maintenance and Spreads NaturallyOnce established, this aster is drought-tolerant and spreads gently by rhizomes to form attractive colonies, making it excellent for naturalistic plantings and erosion control on shady slopes. Supports Overwintering InsectsThe stems and basal foliage provide winter shelter and nesting sites for overwintering insects, including native bees that nest in pithy stems.
