Houseplant suggestions for a hot / cold porch
I have a south facing glass unheated porch at the front of my home with no ventilation/windows, that I imagine gets to 30degrees on a hot day and goes down to 5-10degrees in winter. I'd like to put some greenery in there, but I imagine most plants will suffer from leaf scorch or not like the cold. I read somewhere once that some cactus and possibly succulents can handle the differing temperatures, in fact some, having a cold spell in winter, will produce more flowers in summer.
Anyone got any suggestions please?
