This darkly beautiful wild flower is one of the many species of penstemons that grow throughout the Rocky Mountains.
The plants often have a number of flower spikes and grow in montane, subalpine, and alpine open forests, clearings and on roadsides. Penstemon whippleanus grows up to 20 centimetres in height and is a welcome sight when many of the earlier wildflowers are beginning to die back.
This penstemon can be found in the Rocky Mountain National Park. It flowers late in the season - from the end of summer and into autumn
The specimens shown on this page were photographed in Rocky Mountain National Park in late August .
