Mountain Phlox (Phlox austromontana)

General: Mountain Phlox (Phlox austromontana) is a mounded perennial forb or subshrub with tubular flowers that start out white and age to pink. The flowers are salverform (consisting of a narrow tube with flat spreading terminal petals) to about 1-inch diameter with yellow stamens. There are few hairs on the base of corolla and on the sepals (not densely hairy) and the calyx membrane is keeled. The needle-like leaves are fairly stiff with hairs on dorsal surface (not glandular) and a bristle at the tip.

Mountain Phlox is an uncommon component of vegetation communities in dry, well-drained gravelly and rocky areas in the lower and middle-elevation mountains of the Upper Sonoran (Pinyon-Juniper Woodland) and Transition (Yellow Pine Forest) life zones.

Around Las Vegas, look for Mountain Phlox in the mountains of Gold Butte National Monument, the Mormon Mountains, Zion National Park, Grand Canyon National Park, and mountains in Claifornia, but not on Mt. Charleston.

Family: Phlox (Polemoniaceae). Also called Desert Mountain Phlox and Desert Phlox.
