The var. albifluvis is a rare variety limited to northeastern Utah and northwestern Colorado. It is up to 30 centimeters tall and produces lavender or light blue flowers. The flowers are pollinated by bees. This variety is a candidate for federal protection because it grows on oil shale, a common source of petroleum.
