Tushar Penstemon (Penstemon xylus, previously named Penstemon tusharensis) is a petite yet striking perennial native to the high elevations of Utah's Tushar Mountains. Its mat-forming habit and vibrant bluish-purple flowers make it a unique addition to alpine and rock gardens. Adapted to harsh, rocky environments, this species thrives in well-drained soils and full sun, requiring minimal water once established.

Ideal for gardeners seeking resilient, low-maintenance plants, its flowers attract native pollinators, while its compact form provides ground cover in challenging landscapes. Given its rarity and specific habitat requirements, cultivation for landscape use is in its early stages. This plant has great potential to be a lovely, unique addition to native gardens in Utah!
