One of them has that greyish green and two has the light green color like grass. They just keep producing growths and before i know it i have specimen plants that won't bloom.
I have to wonder if a winter chill would help. Much like the Phals and some cattleyas benefit from. Mine do live in a cool greenhouse in the winter. I know NYC's likely don't get a chill but I think it encourages blooms in many species.
