Penstemon harbourii

Penstemon harbourii

Penstemon harbourii (Harbour's Penstemon)
Plantaginaceae (Plantain Family)

Alpine. Scree. Summer.
Cross Mountain Trail, July 2, 2004 and July 15, 2013.

The plant pictured at top left and above is about two feet in diameter and each flower is nearly an inch long. It was difficult to get to this beauty stretched out on a steeply sloping scree slope at 12,000 feet.

The second photograph at left shows a very young plant establishing itself.

Leaves of P. harbourii are about the length of the flower, light green, often red-bordered, and wedge-shaped.  Buds are tight, wine-colored cylinders.

J. P. Harbour collected plants in the summer of 1862 in Colorado with famed botanist Charles Parry, "King of Colorado Botany". (More biographical information about Harbour.)
