Blue Moon Wisteria
Yellow Hedysarum

Blue Moon Wisteria is a striking, flowering vine, and the hardiest of the wisterias. Up to three times in one growing season you can expect showy, fragrant, lavender-blue flowers.

Make sure you plan your site as this vine requires a structure to support its mature weight. Try planting close to a post, trellis, or fence.

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.
