This wetland flower is found primarily along stream banks, moist grasslands, and forested wetlands form Alaska to California.

This is a favorite for native bees and butterflies carving out an important niche for this species.

This perennial aster is hardy on the west coast and spreads by rhizomes.

In colder climates, it may act like an annual spreading by seed.

Meet this aster’s need for moisture and sunshine, and it will do well.

The stalks are tall and airy with sparse foliage, but the flowers are quite nice.

The dainty flower heads have blue to violet outer rays, and the small tubular central flowers that may be white on occasion but are generally yellow.

This is a valuable plant for wetland habitat. USDA zones 5-9.
