Penstemon azureus
is a species of penstemon known by the common name azure penstemon. It is native to the mountains of Oregon and northern California, where it grows in coniferous forests and woodlands. It is a perennial herb, woody toward the base, with many thin branches reaching up to about 70 centimeters in maximum height. The oppositely arranged leaves are linear or lance-shaped, the ones higher on the plant clasping the stem. The flower cluster produces several hairless tubular flowers in shades of blue to lavender measuring up to 3.5 centimeters long.
