Aka Dockrillia rigida, this Dendrobium is an Australian native. It can handle high light conditions, which make the leaves turn reddish, but doesn’t need that much light to bloom. It doesn’t really have any seasonality, as the leaves send out buds when they mature. It continues to grow all year, rather than only during the warmer months. As orchids go, this one’s as idiot-proof as they get — right up there with Restrepias.
