Also known as the desert Indian paintbrush, linearleaf Indian paintbrush,  narrow-leaved Indian paintbrush, and Wyoming desert paintbrush, this is one of the tallest of North America's Castilleja species, reaching upward to four feet and sometimes growing in such density that they can appear more like a shrub than the typical, low-growing singular forb wildflower one would expect to see among Indian paintbrushes. These unusually orange (they are usually red) beauties were found blooming in profusion in Utah's Arches National Park.
