Indigo bush, Psorothamnus fremontii, is currently exploding in bloom throughout Red Rock Canyon. You will see brilliant dark blue to purple flowers growing on the tops of this 2 to 6 foot gray-green shrub alongside SR-159 and the Scenic Drive. If you get close to one, gently touch the leaves and stems of the indigo bush to experience a pleasant smell. The flowers and stems of indigo bush were smashed by Native Americans to create a yellow dye.
