Pennsylvania Cinquefoil
Yellow Hedysarum

Pennsylvania Cinquefoil is well suited for naturalisation projects as it is a wildflower native to North America. It is widespread and can be found growing in rocky soils at higher elevations in the mountains and foothills, as well as the dry prairies. The Pennsylvania Cinquefoil is capable of growing in cold, harsh conditions. The bright yellow flowers are found at the top of long stalks in small dense clusters and are ideal for attracting pollinators.

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.
