Woolly Prairie Clover: A Southwestern Native for Water-Wise Gardens
If you’re looking to add some southwestern charm to your water-wise garden, woolly prairie clover (Dalea lanata var. terminalis) might just be the native gem you’ve been searching for. This lesser-known variety of prairie clover brings the drought-resistant qualities and pollinator appeal that make Dalea species so beloved by native plant enthusiasts.
What is Woolly Prairie Clover?
Woolly prairie clover is a perennial forb—essentially a non-woody flowering plant that comes back year after year. As its common name suggests, this plant features a distinctive woolly texture that helps it thrive in challenging southwestern conditions. You might also see it listed under its scientific synonyms Dalea glaberrima or Dalea terminalis in older gardening references.
