|I was wondering if Salvia greggi/ Furman's Red Sage/ would work as a container plant on my deck? I doubt it would survive winters in our yard here in Nashville. I don't know if it will survive being brought into the garage when it turns extremely cold, either, but I'd like to try having it on our deck. Should I pick a particularly large pot for it to grow into, or does it prefer closer quarters, i.e. sort of|
|It should do fine in a container for the summer, in winter wait until late fall to bring it inside, keep it very cool but above freezing, and just barely water so the soil does not go bone dry.
This can be up to three feet tall and about 18 inches wide, almost shrubby, so you don't want to go too small on the container. Size is not as important as the drainage. The main consideration is that the soil mix must be well drained. It blooms more prolifically with adequate moisture so you do not really want to drought stress it, but the soil should not become saturated.
This plant is actually rated hardy to zone 6 by some sources and since your zone (going by the zip code) is 6B or the warmer part of zone 6, it might make it for you outside in the right spot. Probably the most important factor in surviving winter would be a well drained location -- in heavy or poorly drained soil it will die out in winter for sure.
Good luck with your sage!
