Upright Prairie Coneflower
Yellow Hedysarum

Upright Prairie Coneflower is a native perennial wildflower known for its vibrant flowers, which range from golden yellow to dark rust-red with yellow edges. Rising on tall, slender stems, the flowers’ drooping petals surround a central cone. They bloom from midsummer into fall, attracting butterflies, bees, and other pollinators. After blooming, the florets on the cone eventually develop into seeds, which provide a food source for birds.

Its upright growth habit allows it to grow in clusters, creating a striking display. Due to its deep taproot, Upright Prairie Coneflower is drought tolerant, making it well suited to dry areas and xeriscape gardens. Low-maintenance and deer-resistant, this wildflower is a great choice for adding vibrant color and ecological value to any landscape.

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.
