General: Utah Butterflybush (Buddleja utahensis) is a dense shrub with small, blue-gray leaves that are elongate, have wavy margins, rolled edges, and are covered with thick woolly hairs. Yellow flowers occur in globular clusters along distal portions of outer stems.

Utah Butterflybush is an uncommon component of vegetation communities in dry, well-drained gravelly areas on bajadas into the lower mountains in the Upper Sonoran (Mojave Desert Scrub) life zone.

Around Las Vegas, look for Utah Butterflybush dry areas with gravel and rocky soils formed of limestone or volcanic rocks. While uncommon, look for them on Fossil Ridge at Red Rock Canyon NCA.

Family: Figwort (Scrophulariaceae). Formerly Butterfly-bush (Buddlejaceae).
