Purple Prairie Clover is a native perennial wildflower known for its striking purple blooms. The flower heads grow as dense spikes on tall stems, with each flower head containing many tiny blossoms. Blooming for 4–6 weeks in the summer, it attracts a variety of pollinators, including bees and butterflies.

The high protein content of the Purple Prairie Clover makes it excellent forage for wildlife and birds like to feed on its seeds. As a nitrogen-fixing plant, it enriches the soil, improving fertility and benefiting nearby vegetation. These ecological contributions make it a great choice for pollinator gardens, prairie & rangeland restoration, naturalization, and re-vegetation efforts.

This drought and heat-tolerant plant thrives in various soil conditions, including rocky soil, making it remarkably easy to grow in challenging environments.
