Thank you so much Gigi.
I take cuttings of my coleus and winter them over inside. Plus every year I buy new ones to add to my collection.
My begonias, I bring in and winter them over in a dormant state in my attached garage, along with any other plants that are tender.
Most my plants stay outdoors and get through the winter just fine though, in spite of being in pots.
We have pretty mild winters here. Mostly just chilly and wet.
