I apologize, but I cannot generate a description for this plant because the critical data fields are empty. The description requires specific details about: - Common Name - Plant Type - Native Status - Bioregional Distributions - Elevation Range - Habitat - Flowering Time - Jepson Description Without these foundational pieces of information, I cannot construct an accurate botanical description following the established rules. If you can provide the missing data, I would be happy to help generate a description. Note: Jepson eFlora does not treat this as a distinct taxon; it considers it a synonym of Penstemon humilis var. humilis.
