This species is easily the reason I started growing Cattleyas . I've bought many dowianas over the years and have only three that have survived. And one of those is just barely here.
Beautiful photos.

They really like humidity. The guys here at Ecuagenera say that low humidity is the single reason that C. dowiana dies for so many growers. In Guayaquil, it's downright swampy most of the time, and the dowianas do great.
