I don't think my cattleya orchid, jewel box, is a dwarf version. It is also about three years old, but taken from a cutting at a local orchid farm. When he took the cutting, he said that there were a couple of pseudo bulbs that had flower sheaths at the top, but one of them died, and I sort of pulled it open and didn't see any flower bud left in there. The pseudo bulb that's blooming now is a little over a year old. I wonder why yours is reluctant to bloom. I can't quite see in the photo if that taller pseudo bulb has a flower sheath or not. I see the one in front is creating one. I've seen that different varieties react differently to Temperature light and air movement. I'm sure yours will bloom… Eventually. Lol.
