Well, I'm in no zone to think of collecting. Frost? What's that? Altho, 35* a few times this winter and that's just way too cold. I did not in fact get the blue-ish one - they were gone - which is a good thing. Impulses just don't work out for me at all. I did impulsively get another sage, but its a bright orchid color that I've been needing because everything's getting a tad too dark, so maybe only half an impulse. The people at HD are getting used to seeing me with a cart full of possible pots as I travel through the plants matching and mixing until I can finally make a few rejections.
