On walks along high mountain trails it is common to see a tall plant that appears to have tiny purple flowers at its very top.  A closer look shows these purple splashes of color to be minute, drooping, thin buds.  They puzzle wildflower admirers.  But once the buds swell and burst open there is no question.  Penstemon whippleanus has about as rich a color and as showy a cluster as any flower.  

A close look at the flower will show silvery white stripes through the purple and a multitude of shining hairs on the flower surface.  The hairs impart a silvery sheen to the sunlit flowers.  In certain areas flower color can also range from white to light blue.

Penstemon whippleanus was collected by John Bigelow in the Sandia Mountains near present-day Albuquerque in 1853, and it was named by Asa Gray in 1862.  Bigelow, who has a number of plants named for him, was a member of Lt. Amiel Whipple's expedition surveying for a transcontinental railroad route along the 35th parallel.  (More biographical information about Whipple.)
