This one blooms like clockwork for me. I always say that I am no good at growing Paphs and then this one blooms and makes a liar out of me. There were actually 4 flowers this year, but only 3 made it into the photo.
I've had this plant for 3 years and keep thinking that I need to repot it, but I figure if it ain't broke, don't go fixin it! LOL
