Diagnosis:  Blue sage is a perennial forb with erect stems.  Stems can occur singly or in a group, being either simple or branched.  The slender stems are 4-sided and mostly short grayish-pubescent.  The leaves are 1-3” long by 1” wide and are simple, short-stalked lanceolate.  The leaf margins are toothed to nearly entire with pointed tips.  Roots can descend up to 8 feet. The spike-like inflorescences are long with 2-8 flowered clusters. Petals are blue and rarely white. Fruits produced are 1 or 2 small nutlets. The brown, resin-dotted nutlets contain 1 seed each.
