Penstemon auriberbis
Penstemon auriberbis, commonly known as the Colorado penstemon or Colorado beardtongue, is a species of Penstemon that grows in the shortgrass prairies of southern Colorado and in a few places in northern New Mexico. Although specimens were collected on the 1820 expedition by Stephen H. Long through the area, they were not scientifically described as a separate species until 1920.
The Colorado penstemon has a reputation for being fussy in cultivation, theorized to be due to having precise soil texture and pH requirements, though they are also well regarded for their handsome blooms. In the average European climate, it is most successfully grown in a hothouse to protect it from excessive moisture.
They grow on the plains of eastern Colorado and northern New Mexico in dry, sandy, sandy-loam, or gravely soils. Penstemon auriberbis grows in shortgrass prairie and in sagebrush shrublands from 1200 to 2500 meters in elevation.
