I am surprised you find it easy to grow. I have 2 (1 from Orchid Inn, 1 from a German vendor) and both are cantankerous, slow growers. They are constantly about to croak--which would be a relief for all of us--but finally come round whithout ever blooming--of course.
Has anyone had the same problems with this hybride?
I had 2 LK, presumably of the same cross. One grew quickly to flowering size, bloomed easily, but wasn't fragrant. Something killed it, I forget what. Its sibling was slow as ...use your favorite euphemism. eventually it did bloom, but it was not spectacular, no fragrance either. It was always unhealthy, a mealy bug magnet unlike any paph I have ever seen. It also refused to die. Slow, ungainly, unhealthy, unkillable, vermin-ridden....finally, it succumbed this year without mourning. So, as you can see, LK, like most other paphs, has a variety of growth patterns. Take care, Eric
