I bought a 4" start and plan to direct plant this for the summer. I am in Zone 8b so might be able to stretch the zone if I give it winter protection. I thought I would perhaps split out half of it in the fall to bring inside and surround the remaining in-ground plant with evergreen boughs and perhaps some straw. It may or may not overwinter. Your comment has intrigued me -- how large of a pot do you bring in for winter, and does it then keep bulking out like a perennial? How cool/warm do you keep it over winter? I have a basement which stays fairly cool but has a couple good windows (mostly on the north side so very little direct sunshine, but plenty of light). Or do you keep it in your normal living area? Thanks for any insight.
