Woodland Phlox – Phlox divaricata – native
These small, colorful flowers attract a number of butterfly species and have their roots consumed by rabbits and voles. Varying from blue-violet, red-purple and white shades, this Phlox species produces both fertile and infertile shoots that are fairly similar in appearance. It only reaches eight inches tall when fully mature but can spread 18 inches.
