An orchid called to me from the member's sale table at our SCOS show and sale last weekend. It was like the "Charlie Brown's Christmas tree" of orchids. Still, one cannot have too many Cattleya percivaliana and it was very inexpensive.
Cattleya percivaliana grows in Venezuela and Colombia in the mountains above 4000 feet near rivers. It is a large sized lithophytic plant that grows out in the full sun. It is fragrant and blooms in the fall.
It is a good example of a backbulb culture variation that works well for Catts. The pseudobulbs are staked up and held down with a wire loop on the bark surface so that the backbulbs can't move around. It has the added advantage of not needing to be re-potted after the roots grow. The tricky part is that the bark needs to remain quite dry.
