Oh, I guess the second photo does do a good job displaying their lengths. The one petal I measured was a little over 20cm (8" in freedom units).
I got this plant when it was already fairly large, but unbloomed so it still may go downhill sometime in the future. It gets very strong filtered southern exposure. Nothing special with the medium or watering. It does go outside in the summer (as long as the nights are above 55F, the average summer night here goes down to 60F). My humidity sucks, though when it's outside and the fog rolls in the humidity gets to 100%. Only things that are really unique are the drastic daily changes in temperature during most of the year, and I'm using Klite. For me Klite doesn't make anything grow faster, but the quality of growth is better and now only my ludisia gets rot.
Sorry there aren't.
I'm fairly sure the plant is from Golden Gate Orchids. I saw some of their St. Swithins a couple months ago and I think the only ones they might have left are roth x phil, the reverse of my cross. They had a yellow lip and the petals' stances were closer to a roth's. They were very nice but the flowers were too pale for my taste and I don't like buying previously bloomed/blooming plants.
