A wide ranging genus including classic border perennials in the form of S. nemorosa and S. x sylvestris cultivars. But others vary in their needs from the tall moisture loving bog sage to the drought resistant and short lived silver-woolly S. argentea. The genus also includes S. rosmarinus (rosemary), S. officinalis (common sage) and its variants. Salvias are native to all continents, (excluding the Arctic & Antarctic), with over 1000 species and nearly 300 in Mexico alone. Most will require full sun, with some of the shrubbier species enjoying a sheltered garden position.
Salvia is now an expanded genus, with the recent inclusion of Rosmarinus and Perovskia.
