From my reading so far, walkeriana has about the same range as Cattleya loddigesii. This is in the MIOS journal online. The walkeriana lives as an epiphyte, or as a lithophite, and has constant water on the roots in the sense of rainfall, or moving water such as "streams" not as a stagnant pool. There are pictures of this area, the orchids are totally out in the open, on big grey rocks, no cover, no trees, and they live alongside cactus, and other grass, and even other types of orchids. Huge fields of orchids on rocks. further reading places them in the "cold hardy" or temperature hardy division of cattleyas (27 to 100 F), Hybrids are more likely to be more intermediate. However there is a natural hybrid between walkeriana and loddigesii. I am thinking that I will be potting it in an over sized pot, (to keep in more moisture) in lava with some marble or granite chips, and then will throw it outside in full sun and water it X3 per day like the others. In fact, if anything, the care will be more like the Reccharia/Myrmecocattleya.
