This Calathea will just make it in a warm place outside the hothouse, here in Sydney, although it dies down completely in winter and gets no bigger. It came as Calathea concinna, but that is apparently not a valid name. Anyone know what it really is? I find it hard to get good info on Calatheas. The world expert appears to be Canadian.
I find it hard to believe that among all the experts no-one has a clue about Calatheas. When you managed to identify Cyanastra cordifolium. Oh well!
