A pretty little plant, with smooth, stiffish, toothless leaves and deep bright blue flowers, with a little white at the base of the petals and veined with purple. This is found in damp spots in the mountains, up to twelve thousand feet, in northern places across the continent, and as far south as Arizona.
There are a great many kinds of Pentstemon and some of our handsomest and most conspicuous western flowers are included among them. They are natives of North America, chiefly herbs, sometimes branching below; the leaves usually opposite, the upper ones without leaf-stalks and more or less clasping; the flowers showy, in long clusters; the calyx with five lobes; the corolla two-lipped, with a more or less swollen tube, the upper lip two-lobed, the lower three-cleft and spreading; the stamens four, in pairs, and also a fifth stamen, which is merely a filament without any anther, but is conspicuous and often hairy; the style threadlike, with a round-top stigma; the pod usually pointed; the seeds numerous. The common name, Beard-tongue, is in allusion to the usually hairy tip of the sterile filament. Pentstemon is from the Greek meaning five stamens. This name is often mispronounced; the accent should be on the second syllable and long.
