This species is widely used in gardens and landscapes for its vibrant coloration and its ability to thrive in a variety of soil types, as well as its drought resistance. The Purple Coneflower also boasts medicinal properties, particularly in herbal traditions, where it has been used to boost the immune system and alleviate colds.

The other plants listed, while they may have their unique characteristics and benefits, do not belong to the Echinacea genus.
