Cold sunroom plants?
I have a very large sunroom which gets some heat so it stays above freezing but it is definitely cold in the winter. I got a book about houseplants from the library and I know it is wrong about minimum temperature requirements of many plants since I had many of the plants they say can't survive less than 50 or 45 degrees growing in my backyard or other nearby yards where I just lived (zone 10a) and we had plenty of tempertures below 45 though we didn't get frost. I would like recommendations for accurate houseplant books or websites that don't have wrong temperature recommendations. My other problem is that the sunroom (and in fact my whole house) is in the forest so no plants ever get full light or bright light.
