The purple coneflowers, Echinacea purpurea, and firewheel, Gaillardia pulchella, are beginning to show their stuff.
I've collected and spread seeds from the Echinacea all over the garden over the years, so it has become rather prolific. Purple coneflower is beautiful, relatively shade tolerant, and a great butterfly nectar plant.
Firewheel might be one of our most under-rated native spring bloomers. Everyone goes nuts for the bluebonnets, which I love too, but big fields of firewheel are pretty darn amazing.
