From Mexico comes this small, drought-tolerant, grey-leaved salvia, forming a nice mass to 12" tall x 18" wide. The upright branches are topped with true sky-blue flowers (really, really BLUE) from early summer through early fall. Blue oak sage prefers a very well-drained site in the border or rock garden. This is truly one of our favorite plants we would not garden without. Pot size: 24 fl. oz (709.77 ml)
