There are many types of Salvia. They can be annual, biennial, or perennial herbs, and woody subshrubs. The leaves are sometimes toothed or pinnately divided. The flowering stems bear small bracts, and in some species the bracts are ornamental. Some Salvias have hairy leaves or stems or flowers, and these hairs sometimes give off an aroma when brushed as oil is secreted. The flowers of Salvia are usually tubular with two “lips” – the lower one larger than the upper one – and often fragrant.
