It seems a bit early to me, but it is Minnesota. =)
This is just a light dusting and I don't think there is more in the forecast for awhile, but the forecast does call for cold, cold, cold! We were prepared though and brought in our bay tree (more like teeny, tiny sapling), the one remaining rosemary, and our very leggy sage. Winter indoors is hard on these plants and we lost several last year. Hopefully these three will survive!
