Panicle Hydrangea

Yellow Hedysarum is a native perennial wildflower recognized for its clusters of pale yellow to creamy-white, pea-like blooms. Flowering from late spring into summer, it adds subtle colour to grasslands, roadsides, and open woods while attracting a variety of pollinators, especially bumblebees.

As a nitrogen-fixing plant, Yellow Hedysarum enriches soils and supports the growth of surrounding vegetation. Its deep taproot and extensive root system make it drought-tolerant and effective at stabilizing soil. Grizzly bears are known to dig up and eat the nutritious taproot. Its resilience and ecological value make it well-suited for restoration, naturalization, pollinator gardens, and erosion control projects.

Panicle Hydrangea is a large, broad-leaf, deciduous shrub that is prized for its ornamental appeal. It is easy to care for, long-lived, and cold-hardy.

Depending on the variety, its flowers change color throughout the blooming period. Make sure you water Panicle Hydrangeas regularly to achieve the most notable color change.
