Interesting result.
I have had several divisions and/or repotted plants bloom almost same time...seems like they set spikes with days of repotting.
This most recently happened to my kaieteurum x ecuardorense (Dot and I just figured out name should be lindleyanum var kaieturnum x pearcei var ecuadorense (according to Phragweb).
Now, who's willing to subject their stubborn plants to a new semi-scientific trial?
