Hairy Golden Aster
White Lights Rhododendron (Azalea)

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.

White Lights Rhododendron is part of the Northern Lights Series, cold hardy, and deciduous. In late spring you'll be drawn to its fragrant white blooms. In fall, the foliage turns a beautiful purple-bronze color. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

White Lights Rhododendron should be your next hedge/screen, or plant it on its own as a specimen plant.
