Phlox (Phlox drummondii)
The Phlox plant provides colorful groundcover in your butterfly garden. Its bright, disc-like flowers look like lily pads in a pond of green leaves, beckoning to birds and butterflies to come rest and enjoy the nectar.
These flowers scan the rainbow and are available from white to purple with many shades in between. Phlox has a lot going for them, including looks, fragrance, and attractiveness to butterflies. Other Phlox varieties include upright flower that grows 3 ft. to 4 ft. tall.
