Plant Description: This is penstemon is native to Utah and thrives in poor soil conditions. It is a clump-forming perennial with reddish-orange, two-lipped, tubular shaped flowers atop rigid stems blooming from late spring well into summer.

As plants become dormant in the fall, remove dead leaves and stems.
