When I lived in Iowa the joke was that one wanted to experience all four seasons in one week they just had to live in Iowa for a while. Sooner or later they would have such a week.
Seems to be the case up here in Minnesota as well. After a stretch with with highs in the 70s to 80s even up as high as 90 it's been fairly cool out the past few days. Supposed to warm up again over the week and be up around 80 by this weekend. So far the plant collection seems to be tolerating the cold snap fairly well. If it was getting too much colder I'd bring them inside or cover them up.
I had to turn the heat back on this morning because the place finally got cold enough to need the heat on for a while. I'm not my aunt or uncle who would keep the home in the mid 60s and where sweaters at home when it's cold out. I have been wearing all my heavier long sleeved stuff lately just because once it warms up again I probably won't need them again for a few months.
