Hairy Golden Aster
Early Blue Violet

Hairy Golden Aster is a native perennial wildflower known for its clusters of bright yellow, daisy-like blooms. They bloom from mid-summer into fall, providing late-season colour and a valuable nectar source for pollinators, including a variety of bee species.

Flowers mature into fluffy seed heads and can self-seed readily. Removing spent blooms helps manage their spread, but some people will choose to leave a few seed heads to provide food for birds. Hairy Golden Aster grow in bushy clumps, tolerates poor sandy soils, and once established, are among the most drought-tolerant wildflowers. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping projects.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.

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.
