My D. superbum is once again in bloom - first two buds opened this morning. I have three plants, two of which are going into bloom. Third is a keiki that bloomed last year for only time. This image is from a previous year's bloom
They have a sweet perfumy scent that takes over the grow area. This is the only major Dendro I've had success with (ie. that hasn't up and died on me) I am currently trying with a mini D. abberans, which shows promise.
