Neon Flash Spiraea

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.

Neon Flash Spiraea is a colorful, low maintenance, and multi-purpose shrub.

Late spring to fall you'll be drawn to its vibrant neon red blooms that rest on a neat mound of green foliage. If deer and rabbit are an issue on your property, consider planting Neon Flash Spiraea for its deer/rabbit resistance. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.
