I just brought the planter in and kept it under lights all winter.. it got invaded with mealy bugs.. I cut it back and sprayed the dickens out of it with alcohol.. a few weeks later it died back.. I added some more systemic since I had nothing to loose... added a few seeds in since I was not sure if it was going to come back or not.. don't even remember what I stuck in there.. LOL and then it popped back up like nothing ever happened.. I even had a petunia that stayed ok in the same planter.. was either blue denim or one of those.. but it's more purple then blue... looks like another salvia is growing in there now as well hope it's not red
