C. percivaliana 'Summit' FCC/AOS Xmas in November!

[silken]

Intruder, I checked OrchidWiz. I don't see much difference in culture between labiata and percivaliana. Except it says percivaliana needs quite bright light and won't thrive unless it has it (3500-4000fc), whereas labiate is listed as preferring 2500-3500. I grow a variety of Cattleyas, both species and hybrids and my perciavaliana doesn't get more light than the rest. They both should be kept a bit drier in winter. I always let my Catts dry out pretty much completely before watering except in very warm, bright days of summer, they might get a bit more water.
