Eastwood's monkeyflower is a small trailing or climbing perennial with bright red tubular flowers, native to seep-fed sandstone hanging gardens in desert canyons of the American Southwest. It grows best where it has constant moisture and cool, shaded rock faces, so it is hard to keep in ordinary garden conditions.

About
Erythranthe eastwoodiae, commonly Eastwood's monkeyflower, is a plant that grows in moist areas of sandstone called hanging gardens in the desert canyonlands.
Where it grows
Eastwood's monkeyflower has a somewhat uncertain native range. According to World Plants and Plants of the World Online it grows in five US states, Arizona, Colorado, New Mexico, Nevada, and Utah, and also the Mexican state of Sonora. The Natural Resources Conservation Service (NRCS) list the same five US states, but does not have a precise location for the populations in Nevada. However, according to NatureServe, it is only found in Colorado, Utah, and Arizona. According to NatureServe there are eight populations in four western counties, Montrose, Mesa, San Miguel, and Delta. Using NRCS data, it is just found in San Juan County the northeastern most county of New Mexico. It is much more widespread in Utah, growing in five southern counties, and is recorded in Apache, Navajo, and Coconino counties in Arizona.
