Echinacea, Purple Coneflower
Easy to grow perennial, beautiful as an ornamental or for herbal use. Renowned as an immune system stimulant. The flowers are large, and held on long, sturdy stems. Nurseries are now carrying a number of novelty hybrids and clones, but really, the original wild plant is just as decorative, and has stronger medicinal action. This native American herb of the prairie has been over-harvested in the wild, so it is especially important to grow in the garden. 3' tall clumps increase in size over the years, but are not invasive at all. For herbal use, the roots can be dug at the end of the 2nd year. Or just tincture the fresh leaves and flowers and leave the roots undisturbed.
