Blue Mountain Penstemon, also known as Rydberg’s Penstemon, or Meadow Beardtongue or Penstemon rydbergii, displays vibrant blue-purple flowers and can grow up to two feet tall. Blue Mountain Penstemon is a perennial wildflower native to the western regions of North America, particularly in the Blue Mountains of Oregon and Washington. It is adapted to the Intermountain Region and grows native mainly in the mountains on open slopes and meadows with rocky soils. This wildflower produces stunning deep blue-purple flowers that bloom in late spring and early summer. 


This hardy showy wildflower is an attractive and low-maintenance choice for gardeners looking to add color and texture to their landscapes. The pollinator is also palatable and moderately drought tolerant. Its creeping rootstocks make it an excellent option for revegetation of disturbed sites and soil stabilization.
