SALVIA. Sage. Worldwide. This is a huge and diverse group of mint allies, grown both for ornament and for herbal qualities. Those listed below are undemanding perennials and shrubs with usually rough-textured, aromatic leaves. Some form broad rosettes of basal leaves; others have branched, leafy stems. Usually the leaves are paired along the stems. Irregular 2-lipped flowers are borne in dense heads, whorls or spikes above the foliage. They come in nearly every floral shade, including near-black. Culture and hardiness vary widely, though most prefer a sunny spot with well drained soil. Many, particularly natives of California and the Southwest, are drought tolerant.
uliginosa. A densely clumping perennial with many arching 4-6' stems, clothed with narrow, shiny green leaves. Branched clusters of beautiful blue flowers adorn the plant in late summer and fall. Moderate watering. Probably 15oF or less.
