Family, Mint. Color, bluish purple. Calyx, 2-lipped, the upper lip 3-toothed, sometimes entire. Corolla, gaping, deeply cut into 2 lips, the upper straight, slightly notched or entire, the lower 3-lobed, spreading. Stamens, 2 perfect ones on short filaments, at whose summits a thread crosses, bearing at one extremity a single anther-cell ascending under the upper lip, and at the other an imperfect but pollen-bearing anther, descending. This separation of the anther-cells by a transverse filament is characteristic of sages. Leaves, from the root, deeply cut, lyre-shape, sometimes entire; on the stem, generally a single pair, small and narrow; near the flower, a few, bract-like. May and June.
S. officinalis is the common aromatic sage of the gardens, with purplish blue flowers in whorls about the stem. The name is derived from salvus, "in good health," from supposed curative properties. An old writer says: 'It is good for the head and brain. It quickens the memory and senses. No man needs to doubt of the wholesomeness of sage."
Family, Mint. Color, purple or white dotted with purple. (See White Flowers, p. 121.)
