C. walkeriana 'Blue Moon' x C. maxima var. coerulea 'Blue Sky'
Interesting novelty cross here! Not sure what to expect. Walkeriana tends to lend quite a bit of substance to its hybrids, something which maxima definitely lacks. These should flower in 2-3 years, and be compact sized Cattleya. Keep them in bright light and dry well between watering.
