WILD BLUE PHLOX
Rich deciduous forests, usually beech-maple-hemlock but sometimes oak-hickory, especially in moist areas such as ravines and floodplains. The northernmost record in the state is from St. Martin’s Island, Delta Co. Our populations have been referred to subsp. divaricata.
In Michigan, both this species and P. pilosa have gland-tipped hairs on the calyx. The flowers are usually blue in P. divaricata, quite different from those of P. pilosa, but white-flowered plants occur with some frequency (f. albiflora Farw.); plants with reddish-purple flowers were named f. purpurea Farw.
