Care Guide
Planting
Plant your Rough-leaved Aster in partial shade, which is ideal for this native western perennial. Space plants about 2 feet apart since they reach 2 feet in height at maturity. Plant in spring or fall to give the plant time to establish before extreme temperatures arrive.
After Planting
Water regularly during your plant's first growing season to help it establish a strong root system, then gradually reduce watering frequency as it matures. Rough-leaved Aster is a perennial that will die back in winter as part of its natural dormancy cycle, so don't be alarmed when it disappears - it will return in spring. Cut back dead growth in early spring before new growth emerges.
