Did you know

  • The genus name Penstemon means 'five stamens' in Greek — four are fertile; the fifth is a sterile staminode covered in yellow hairs that gives the whole genus the name 'beardtongue.'
  • Hairy beardtongue is one of the most cold-hardy of all eastern penstemons, surviving winters as far north as USDA Zone 3 (−40°F).
  • The tubular, two-lipped flowers are designed specifically for bumblebees, which must force their way inside to reach the nectar, picking up pollen in the process.
  • Unlike many penstemons, P. hirsutus thrives in the humid summers of eastern North America, making it among the most garden-adaptable species for the eastern US.
  • The entire plant — stems, leaves, and calyx — is covered in fine glandular hairs, giving it a slightly sticky texture and the 'hirsutus' (hairy) species name.
