Hi all, I'm looking for inspiration for a houseplant that is happy with both cold and heat. It's for a south facing garden room, very bright and sunny. It's my office in the day, so I heat it with an electric heater that makes the air quite dry. But even though it's insulated it gets very cold at night, and on my non-working days. Any ideas for a biggish plant that would tolerate this? Preferably nothing spiky! I put my lovely peace lily out there but within two days it looked very unhappy.
Thanks in advance.
