California aster, also known as Pacific aster, is a long-blooming native perennial valued for its adaptability, extended season of color, and strong pollinator support. Upright stems carry open, daisy-like flowers in soft shades of violet, pink, and pale white, each centered with a bright yellow disc.

Blooming from early summer well into fall, this species provides reliable nectar over many months—making it especially useful in pollinator gardens and restoration plantings. Butterflies are frequent visitors, and the open flower form is accessible to a wide range of native insects.

California aster thrives in full sun and tolerates drier conditions once established, making it well suited to meadow gardens, native landscapes, and prairie-style plantings. Its flexible height and natural form allow it to blend easily with grasses and other native perennials.
