Penstemon

Penstemon

Penstemon Penstemon gloxinioides has trumpet-shaped flowers with the mouth of the trumpet flaring out into an upper lip of two petals and a lower lip of three petals as in other members of its family. The name comes from the words for five "pente" and stamens "stemon" but only four of the five produce pollen. The single sterile stamen is about the same length as the others and is usually yellow-bearded near its tip. [CH] {MV}
