Yellow Hedysarum
Hairy Golden Aster

Yellow Hedysarum is a native perennial wildflower recognised for its clusters of bright yellow pea-like blooms. It adds colour to grasslands, roadsides, and open woods. It is also a nitrogen fixer, which helps improve soil fertility. Because of its deep root system, it contributes to slope and soil stabilisation.

The plant provides forage for wildlife and cover for small animals, especially its roots. Its flowers attract pollinators such as bees.

Yellow Hedysarum plays an important role in prairie and foothill ecosystems. It is well-suited for ecological restoration, naturalisation, pollinator gardens, and erosion control projects.

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.
