Sage (Salvia officinalis)
Sage is a medium-sized, 2-foot-tall hardy perennial herb. The 2 to 3-inch long leaves are thick, opposite, oblong, and pointed. The stems are semi-woody and square. Color varies by cultivar, from grayish green, to variegated green and yellow, or green with purple and white. Spikes of purple flowers are produced on mature plants.
