Yellow Hedysarum
White Lights Rhododendron (Azalea)

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.

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.
