I stuck mine outside in the 35-40 degree nights to see if that will make it bloom. Mine is 4 growths that look like b.s. to me. But I've only had it since the big Paph House sale. I left it outside for over a week in the cold, so we'll see!I hope you have better luck with yours Candace!!
I have a few other primaries with stonei as one parent and I don't have problems blooming them. Lady Isabel, Imperial Jade and Mount Toro. Now only one of them, Mount Toro, is cross-sectional but had no problems with deformity in this cross.I just read about one of Luk Luk's parents, P. stonei, on paphs.net. It was described as slow to grow and hard to flower, and known to pass those attributes on to its offspring. Fantastic flower though. Has anyone had any luck with stonei?
