ClassificationPenstemon Penstemon Ericopsis Caespitosi
GeneralProstrate Penstemon. In J. Barrell’s 1969 Flora of the Gunnison Basin, he comments that between P. crandallii and P. procumbens “these two plants must be regarded as separate species” and are “widely separated in the Gunnison Basin by habitat, altitude and geography”. The commercial offering of P. procumbens has been erroneously labeled as P. caespitosus ‘Claude Barr’. Blooms: June and July.
AntherBlack, opening narrowly.
StaminodeOrange bearded, included.
Leaves2 cm (3/4”) long & 6-7 mm (3/16”) wide, green, flat, smooth, obovate, strongly reminiscent of Arctostaphylos uva-ursi (kinniikinnick) with a short mucro (slender, pointed tip), sometimes “longer and oblanceolate to shorter and spoon-shaped, but always the petioles (stems) are connate (wrapped around the stems), maintaining the connation even when there is an auxiliary stem arising from one of the leaf axils.” J. Barrell
