Thank-you all for your help.
There is no copper hue on the plant at all, so I think it must be Kalanchoe bracteata.
I have Googled it to find out how tall it grows, but various sites give varying heights, from 12 inches to 4 feet!
Does anyone know how tall it becomes?
It will determine where I put it.
I like it when new plants just turn up like this one did.
