I left my dusty millers in the ground - 1 mile south of me the nursery owner says we're Zone 4/5 and 1 mile north of me the other nursery owner says we're zone 5B so there's a range of 1.5 zones in two miles - my Dusties died off over the winter and came back in the spring MUCH bushier and taller than they were at the height of their growth last year; literally double to nearly triple the size of their best the season before. I did NOTHING special to aid in their survival. Since they're sold for about 25 - 50 cents each here in the spring as annuals I figured it would be less work to buy new ones. I'm now totally sold on these plants as tender perennials here much like many of my others (watch we'll have a horrible winter and the weather will make a liar out of me!)

Mine are in pots on my deck (2 different varieties). Can I bring them indoors for the winter?
