whether this is Penstemon barbatus or Pentsemon cobaea is unsettled in my mind at this time, though I’m leaning toward the latter. Typically the Penstemon cobaea or Wild Foxglove is white or creamy overall, with purple to reddish lines. This has the same shape flower, although the coloring is quite different. Still, I think it is probably a red variant of Penstemon cobaea. even though the plant I photographed at the WIldflower Center did have a sign saying Red Penstemon…. which is quite different in form. Good reason to identify these plants by their genus and species names instead of common names.
