Bring brilliant summer color, elegant texture, and unmatched ecological value to your garden with Purple Prairie Clover (Dalea purpurea)—a hardy, drought-tolerant native perennial that thrives in sunny, well-drained sites. With delicate, fern-like foliage and graceful upright stems topped by thimble-shaped clusters of rose-purple flowers, this legume adds ornamental appeal while nourishing wildlife and soil.
A beloved nectar source for native bees, butterflies, and moths, Purple Prairie Clover is also a host plant for species like the Southern Dogface, California Dogface, Reakirt’s Blue, and Rusty Patched Bumblebee, a federally endangered pollinator. Deep taproots give it exceptional drought resilience, and as a nitrogen-fixer, this plant naturally enhances soil health—making it a valuable member of any restoration, meadow, or low-maintenance garden.

- Nitrogen Fixer: Naturally enriches soil, improving garden health.
- Drought-Tolerant: Thrives in dry, rocky, or sandy soils after establishment.
- Deer-Resistant: Not favored by browsing wildlife.

Planting Tips
- Location: Prefers full sun for best flowering and growth. Adaptable but thrives in dry to medium, well-drained soils (including sandy, rocky, or clay-based).
- Watering: Water regularly until established; then, drought-tolerant.
- Maintenance: Minimal care required. There's no need to deadhead the flowers, as allowing them to go to seed provides a valuable food source for birds. Leaving the stems standing in the fall offers overwintering sites for beneficial insects. If desired, cut back the stems in late spring after pollinators have emerged.
