So, I took all the flowers, tomato plants, etc. down for the Winter.  We have a terrace container garden, so it's nice to get things cleaned out before Winter hits.  This year I decided to leave all the herbs in place and see just how far they'd go.  Not surprisingly, the mild Winter has helped.  I still have thyme & rosemary.  I don't think I'm too surprised about the rosemary, but I always thought thyme was pretty delicate.
