is an uncommon Penstemon occurring on outcrops of the plains of northern
Larimer and Weld Counties. Plants grow to about 12-inches tall. Leaves and stems
are strongly pubescent. Flowers are bell-shaped, with an expanded throat.
Fuzzytongue Penstemon has a staminode, or sterile stamen-like structure,
that sticks out beyond the petals and is covered with long hairs. Anthers are
glabrous (hairless). Look for Penstemon eriantherus at Soapstone
Natural Area north of Fort Collins.
