Pineapple sage is an herbaceous perennial in the Lamiaceae (mint) family best grown as an annual in colder regions. It is native to Mexico and Guatemala and grows 3 to 5 feet high and 3 to 4 feet wide. The genus name Salvia is derived from the Latin term salveo, which means ‘be well’ and refers to the plant's medicinal properties.
Pineapple sage will grow best in full sun in moist, well-drained soil. Although somewhat drought tolerant, leaves will begin to drop with insufficient moisture. Although the plant will die down to the ground with the first frost, it will grow back the next spring in mild climates. It is not recommended to grow pineapple sage from seed unless started indoors and set out as a well developed plant. Stem cutting is another propagation strategy. 
 
It is used in teas, potpourri, cream cheese, jams and jellies
