they do not like to be, too dry, too wet, too warm, too cold, too dark, too bright or too draughty they also don't like to have dead leaves or buds taken off, but don't like to grow new ones if there are too many dead/done ones.
They are not indoor plants - they actually love cold weather and so are the perfect plant to have outside this time of year. They don’t like much water either - I just give mine a drop when the flowers start to droop and an hour or so later you can see them revive. Too soggy and they rot. I have them in my window boxes and planters - they are covered in a dusting of snow at the moment, but I’m confident that when the snow has gone they’ll perk back up again.
