I first met Dalea purpurea when I walked The High Line in New York city. I had no idea what it was and it fascinated me. It turns out it is a native perennial prairie plant. I soon brought home a plant from work and planted it on the south side of my house. It is doing great! The flowers look like elongated purple clover blossoms. They are great at attracting pollinators. It grows 24-30" tall and has finely cut leaves. Being a legume, it fixes nitrogen in the garden. Direct sow in late spring or start indoors in late winter and transplant when the weather warms up. It will begin blooming the second year.
