Same here.
I have two good size plants of Bulbo echinolabium, bought from different sources and one is only a bit larger than the other and blooms really well. ( Right now in bloom and showing a few more spikes.) The other has not said peep ever in all those years I grow it - right next to the good bloomer.
So, if I only would grow the non-blooming echinolabium, I would think I couldn't bloom it.
