Showy Aster
Early Blue Violet

Showy Aster is a native perennial wildflower recognized for its tall stems topped with clusters of light purple blooms. Blooming from late summer into autumn, it provides an important late-season source of nectar and pollen for pollinators. It also produces seeds that are eaten by birds, extending its value to wildlife beyond the flowering season.

Drought tolerant once established, Showy Aster grows well in urban, rural, and disturbed sites. With its mix of ecological value and ornamental appeal, it is ideal for pollinator gardens, naturalization projects, and ecological restoration.

Early Blue Violet is a low-growing native perennial wildflower valued for its striking early-spring blooms. The flowers range in color from vibrant blue to deep violet, often marked with pale highlights and fine white hairs. They provide an important early nectar source for pollinators and serve as a host plant for several fritillary butterfly species.

It spreads by both seed and rhizomes, gradually forming small colonies. Its dark green, heart-shaped leaves add ornamental appeal, and the plant shows some resistance to deer browsing. Early Blue Violet is well-suited to naturalization projects and pollinator-friendly gardens, and has also been used in coastal butterfly habitat restoration in the Pacific Northwest.
