Dalea purpurea is a species of flowering plant in the legume family known as purple prairie clover. Native to central North America, purple prairie clover is a relatively common member of the Great Plains and prairie ecosystems. It blooms in the summer with dense spikes of bright purple flowers that attract many species of insects.

Distribution

It is native to central North America, where it occurs from central Canada to the southeastern and southwestern United States, except for the east and west coasts. It is a common and widespread plant within its range, especially on the Great Plains. In 1804, Meriwether Lewis collected a specimen in Nebraska.

The leaves are a few centimeters long and are divided into 3 to 7 narrow leaflets. The inflorescence atop each stem branch is a spike up to 7 cm (2+3⁄4 in) long containing many purple flowers.
