Black-Eyed Susan
Hairy Golden Aster

Black-Eyed Susan is a striking native wildflower known for its bright yellow, daisy-like flowers with dark center disks. With deadheading, the plant can bloom for an extended period, from mid-summer to early fall. These cheerful flowers attract a variety of pollinators, including bees and butterflies. Adding to its ecological value, the plant also acts as a host for the Wavy-Lined Emerald Moth (Synchlora aerata) and the Silvery Checkerspot (Chlosyne nycteis) butterfly.

While it is typically a short-lived perennial or biennial, the plant freely self-seeds. This allows it to persist in the landscape, particularly in natural areas where it can spread and establish itself. This plant is drought-tolerant, salt-tolerant, and deer and rabbit-resistant, making it ideal for challenging environments. The Black-Eyed Susan is well suited to wildflower gardens, pollinator gardens, as well as slopes, banks, and naturalized areas.

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.
