In August 2010 I got four Cattleya aurantiaca seedling from Ian's Orchids on EBay. I put two in rocks and two in bark and spread them around the greenhouse. This particular plant grew well and actually bloomed the next year. It is one of the ones in bark and is partially shaded by mounted orchids.
Cattleya aurantiaca grows in Mexico and El Salvador in rain forests. It is cool to warm growing and blooms in winter and spring.
This plant was put in bark over peanuts in a 2 1/2-inch plastic pot. There were three pseudobulbs and a new growth. As the new growth developed it got tippy so I put that in a larger clay pot with rocks. The pseudobulb that is blooming now is over the edge of the plastic pot and has roots down in the rocks. It is much taller than last year's growth and there are quite a few flowers.
