Blue Moon Phlox or Woodland Phlox, Phlox divaricata, is a woodland phlox with delicate, fragrant, lavender flowers that attract hummingbirds and butterflies in April and May. This plant can form large colonies as the weak stems flop over and root at the nodes. Although it can tolerate deer browse, it can succumb to nibbling bunnies. Grows best on forest edges and shores of rivers or lakes. Prefers a moist soil, but can tolerate all soil types. 1 gallon container.
