The unselected types flower freely in summer producing showy blue, pink or white spikes that attract many bees. Several cultivars have been selected that flower rarely, if at all, and are therefore more suitable for the production of culinary herb.

Sage grows naturally in areas from Spain to the Balkan peninsula and Asia minor. The major world producers of sage are Yugoslavia and Albania.
