dove i think the key to salvia greggii winter survival is a warm exposure-southern, protected-and perfect drainage. mine have survived to -19C, which is about as cold as it gets here lately. there is a greg called cold hardy pink which is esp. hardy. all the forecasts say down to -3C fri, sat, sun. so garden is done and great cleanup and compost festival can begin-yay. there is something so godlike about running a really hot compost heap-and on the eighth day he made compost.
