10. Coreopsis
Coreopsis, commonly called Tickseed at garden centers and greenhouses, is a cheerful hardy perennial that, while cultivated, is native to the United States. The hardy perennial thrives as a wildflower throughout much of the US. It features delicate green foliage reminiscent of annual Cosmos plants, and bright daisy-like flowers with yellow centers.
These perennial flowers are also valuable food to pollinators and some caterpillars. That means, they are an excellent insect-friendly addition for any landscaping project. Make sure you add them to your list of flowers for your landscaping project!
