Douglas aster blooms profusely in late summer to fall, providing important late-season pollen and nectar for pollinators. Douglas aster is an herbaceous perennial wildflower in the aster family. It usually occurs in wetlands and moist locations in the Klamath-Siskiyou area and will look its best with access to year-round moisture. It is typically a coastal species in the Klamath-Siskiyou, but can also occasionally be found inland. Douglas aster is native to the Western United States, from Alaska to California, and over into Idaho and Montana. It is a much-loved native aster and is common in Northwest native plant gardens. Douglas aster grows very quickly, putting on a lot of vegetative growth and flowering in its first year. It can grow as tall as 3′. Its robust growth habit can be beneficial for many locations, but may be a limiting feature for small yards. Douglas aster spreads by creeping rhizome and will become a cluster of tall, flowering stems over time. Douglas aster is highly attractive to many pollinators, including butterflies, bees, and pollinating flies and wasps. Deadheading prolongs the bloom time.
