I wonder what inside temps you keep. Also whether you use humidifiers. Maybe the dry air will give rust a hard time.
When I lived in Potsdam NY I grew a huge table full of plants in front of a large double glazed south facing window. We kept the house around 60 degrees. Our yearly fuel bill was the same as friend's bill for a month. In Spring and Fall we used oil heating, just enough to stop the pipes freezing. In winter we had a wood stove in the basement. I used to dry the washing down there. A few times I put (Australian towelling) diapers on the line, but freezing rain made it impossible to get them off. The ice sublimated off and they were so soft and fluffy.
Anyhow at Christmas I had flowering wonderful tuberous begonias, impatiens, and for a while a tomato plant. In those days I didn't know daylilies were so interesting.
We have different problems here. This morning I looked forward to seeing if I actually had 'Border Bride'. A wallaby or a possum had eaten the scape down to 6".
