Third bloom of the season--although the season is typically in the late winter/early spring in my experience. One of the parents of the famous old hybrid Gatton Sunray.
Wonderful! I am still waiting on my pulchellum alba, which was only a keikei (apparently still a rare variant), but this is one of the most rewarding Dendrobium. Gatton Sunray is again available and probably easier, if not only from its smaller size. I bet your plant love the Indiana Summer!
