Appearance and growth The sage genus includes annual, biennial or perennial herbaceous plants, subshrubs and shrubs. Sage grows in clumps with numerous upright shoots and reaches a height of 30 to 50 centimeters. The square stems are woody in the lower part and branch out. The leaves have long stalks, narrow to lanceolate, up to eight centimeters long and two centimeters wide. They are dull green and have dense gray-felted hairs. When crushed, they give off a camphor-like smell. Depending on the species and variety, purple flower clusters appear on loose spikes in whorls on the plant from May to September. Among the numerous varieties, however, there are also some with pink or white flowers.
