Purple Prairie Clover
Dalea purpurea
Family Fabaceae

Purple prairie clover blooms like a tiny celebration — rose-purple thimbles ringed by a moving halo of golden stamens, and around them a hum of bees, including prairie specialists that seek this flower out. It's the kind of native jewel that makes visitors stop and ask.
Underground it's quietly improving your soil, fixing nitrogen from a taproot that laughs at drought in the leanest ground. Start with small plants — it resents moving — and give it a few seasons; what you get back is a long-lived resident of the sunny dry meadow. Patience, rewarded.

A refined prairie native — slender stems topped with rose-purple thimble flowers ringed by a halo of golden stamens, buzzing with specialist bees in midsummer. It fixes nitrogen, thrives on lean dry soil from a deep taproot, and feeds pollinators, butterflies, and seed-eating birds. Slow to establish (building that taproot) and transplant-shy, so start small. A jewel of the tallgrass prairie palette.
Spacing- 12-15 in

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.
