The flowers of Phlox longifolia vary from white to pink and purple and are large enough (and the overall plant tall enough at four-to-ten inches) that most hikers notice them immediately. Phlox longifolia is often in small patches on barren ground in the forest or on open sandy soils and thus their presence is even more marked.  This long-leaved ("longifolia") Phlox bloom for a number of months in various parts of canyon country.

Nathaniel Wyeth collected the first specimen of Phlox longifolia, probably on the return portion of his 1832-1833 first trading trip to the Pacific.  He gave his collection to his friend and eminent botanist, Thomas Nuttall, who named this plant in 1834.

One key to distinguishing this Phlox is the keeled, white membrane between the lobes of the green calyx (the striped vase-like structure surrounding the base of the pink floral tube).
