i lost all of these i planted to our first frost of the year. will they come back in the spring ? plant files say hardy to zone 7 i thought that meant they were okay in the cold. now i dont know how to pick salvias for my zone (9a)
A lot of these sages, including the newer ones that have small tubers like S. lineata, S. stolonifera, S. clinopodioides would benefit from the drainage provided by incorporating pellets and chips of expanded slate products. This would also be true for xeric sages like the S. greggii, S. lycioides, and other species of section Flocculosae
Just be sure the melted parts extend to the tubers. Kathe Navarez thought she had lost hers, but it came back up from the small tubers the next spring, then went crazy! After bloom stops in the autumn, the foliage feeds the tubers, as I have been observing with the smaller pots when I inspect the roots every 7 - 10 days. Stolonifera does the same thing, and clinopodioides, patens, and others should be similar.. If you must repot, use a very fast mix, with lots of pelletized expanded shale, or even perlite. They don't need much moisture, but do need air. Don't let the pots freeze solid, though.
