Showy perennial, native to a number of states in the Rocky Mountains, where it grows in sage brush and coniferous forest communities. Forming clumps of neat evergreen foliage 8 – 10 inches tall by 36 inches wide. Mid to late spring brings flowering stems 2 foot or so above the foliage with deep blue-purple tubular flowers. Considered one of the easier to grow, tolerating heavier soil and moisture better than many Penstemon species. Still, good drainage is best with little summer water once established. Plant in full sun to light shade in hot regions. Very cold tolerant. Penstemons are attractive to hummingbirds, bees and butterflies.
