I bought some seedlings of P. rothschildianum in 1989, grew them under lights until 1998 (when a tornado necessitated their transfer from my basement), then gave them to our college greenhouse. The first one flowered last year. The effect on a number of people, upon seeing the flowers, made it worth the wait.

I have grown about 20 seedlings of Paph Rothschildianum over the past 20 years. Under my conditions (home under lights), all but two have grown very slowly and show no inclination to bloom. One has grown almost large enough to bloom. One has grown very quickly, bloomed at about 10 years, and has bloomed three times since. All were in the same kinds of pots, in the same media, under the same lights. Over the years, there have been noted clones which were good performers and are responsible for the bulk of hybrids involving Roth. With time, the faster growing, freer flowering clones will predominate. But for now, expect great variability.
