Golden-beard penstemon

Penstemon barbatus

''Penstemon barbatus'', known by the common names golden-beard penstemon, and beardlip penstemon, is a flowering plant native to the western United States. In Spanish-speaking New Mexico and southern Colorado, it is called ''varita de San Jose'' – "St. Joseph's staff".

The plant has spikes of clustered, tubular, scarlet blossoms with yellow hairs on their lower lip; the flowers are very attractive to hummingbirds. It is commonly grown in Xeriscape and conventional gardens, and several cultivars of different colors have been developed.

The late-summer flowering of ''Penstemon barbatus'' coincides with the southern migration of the Rufous hummingbird, and the hummingbirds use the Scarlet buglers as "filling stations" for their long trip south.
