Penstemon strictus is in the foxglove family Plantaginaceae. Commonly known as rocky mountain penstemon, it is native to Colorado, Wyoming, Arizona, New Mexico, and a small area of California. Rocky mountain penstemon is a herbaceous perennial found growing in subalpine areas including pinyon-juniper forests, and open meadows. It is also considered one of the most common penstemon species in the Rocky Mountain area, often forming dense populations of plants that cover forest clearings and bloom in the spring and summer. Because of its vibrant display of blue-purple flowers, coupled with its high drought tolerance, rocky mountain penstemon has been cultivated widely for use in perennial beds and native plant gardens. -- source link
