Salvia guaranitica 'Argentina Skies' (Argentina Blue Sage) - A large 4- to 5-foot-tall herbaceous perennial or subshrub from South America that has ovate, pointed slightly toothed, and hairy light-green leaves that are 4 to 5 inches long and light blue 1 1/2 inch long flowers with green calyces over a long bloom season starting in early summer until first frost.
It grows best in full sun along the coast or light shade inland in a fast-draining soil. Regular watering throughout the growing season. Prune plants to the ground in late winter and divide clumps every few years for added vigor. Fairly cold hardy, surviving temperatures into the 20's so useful as a perennial down into USDA Zone 8.
The Salvia guru, the late Richard Dufresne, noted that this attractive cultivar was introduced into the US trade in 1990 by Charles Cresson of Swarthmore, Pennsylvania from seed he received from Juan Patricio O'Farrell who collected it in the Parana (or Paraua) river basin in Argentina. He also suggests that this maybe the "alba" form of a plant once called Salvia melanocalyx, which he believes is the same as the cultivar now called 'Black & Blue'. The name Salvia comes from the name used by Pliny for a plant in the genus and comes from the Latin word 'salvere' meaning "to save" in reference to the long-believed healing properties of several Sage species. The specific epithet means "of Guara" in reference to this plant coming from Guara, Brazil. We first got this plant from Suncrest Nurseries and grew it from 2000 until 2008 when we replaced it with Salvia guaranitica 'Black & Blue'.
