PlantFiles: Largeflower Sage
Salvia vinacea

I have not grown this plant. Largeflower sage (Salvia vinacea) is native to New Mexico and Texas. It is a low growing suffrutescent (having a woody stem only at the base) plant that is about 30 cm in height. Its stems are slender. The 30 mm long by 25 mm wide leaves are glabrous above, slightly puberulent below and are the same color on the upper and lower surfaces. Usually truncate (leaf tip ending abruptly as if cut off at the end) at the base, they can be decurrent (running or extending downward along the stem). Numerous blooms are produced on short, congested spikes. The 12 to 13 mm long calyx is mostly a deep wine color and is greenish at the base. The calyx pedicel is short and deflexed. The 20 to 22 mm long, dark blue corolla extends far beyond the calyx. The upper lip is oblanceolate. It can be differentiated from Salvia pinguifolia by its (Salvia vinacea's) bloom having a much larger corolla with the upper lip being narrower, a wine-colored calyx, more congested inflorescence and leaves not being a lighter color on the undersides.

I could locate very little information about this plant on the internet.
