Common sage is a semi-hardy perennial that grows to 2 feet high, depending on variety, and has purplish blue flowers. Numerous varieties include broadleaf, clary and pineapple
Sage grows easily from seed. Start indoors three to four weeks before planting. Sage likes full sun and well-drained soil, though it will tolerate poor soil if you allow it to dry between waterings.
If cared for properly, sage can live about five years.
