Description
Purple Prairie Clover (Dalea purpurea), also known as Petalostemum purpureum, is a sun-loving native legume with vibrant, thimble-shaped purple flower spikes that bloom from the base upward. Blooming in early to mid-summer, it brings long-lasting color and fine texture to prairie plantings.
This drought-tolerant perennial grows best in full sun and thrives in dry to medium, well-drained soils. It’s commonly found in prairies, savannas, rocky slopes, and limestone glades. Its narrow, fern-like foliage stays attractive even after flowering, adding texture throughout the season.
Purple Prairie Clover has a deep taproot, making it long-lived and resilient once established. It’s not picky about soil type as long as drainage is good.
The flowers attract a wide range of pollinators, including honeybees, bumblebees, leafcutter bees, and butterflies. It’s especially valuable for native bees and is considered a key plant for the Rusty Patched Bumblebee. It also serves as a larval host for species like Dogface Sulphur and Reakirt’s Blue.
It can be distinguished from White Prairie Clover (Dalea candida) by its narrower leaves and purple blooms, compared to the broader leaves and white flowers of its close relative.
