Salvia roemeriana is a charming and easy-to-grow native sage that lists its primary residence as limestone outcrops in central Texas and adjacent Mexico. I caught my first glimpse of Salvia roemeriana on my 1994 expedition to Mexico, where it was truly love at first sight. Salvia roemeriana is a native woodland sage that forms a small 1' wide rosette of small, dark green leaves with purple veins. In late spring and early summer, Salvia roemeriana flowers heavily, topped with 12" spikes of bright crimson-red, tubular flowers...great for low-flying hummingbirds. Salvia roemeriana has survived 0 degrees F here with no problem and actually reseeds near the original clump...good drainage and a pH above 6.0 give the best results.
