Purple Coneflower: strength and health The flower meaning here is probably the most fitting of all. Purple coneflower is another name for echinacea, a plant with significant medicinal properties. It is believed to be an immune system stimulator and to ward off infections. The flower itself has a large, circular head with long, thin petals drooping off the sides. Both the herb and the root are used in healing products. Thus, giving a friend a purple coneflower is literally saying you want them to be well.
