Buttonbush

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.

Buttonbush is a moisture loving shrub that provides year round interest.

It has round, fragrant flowers resembling small buttons or pincushions. The flowers transform into small reddish-brown fruit that persists into winter while the leaves take on shades of red in fall.

Providing essential food to bees, butterflies, and other insects, this shrub is versatile. Try it in your next shrub border.
