OK, here's a mystery for you orchid experts to help me out with. A week ago I posted a picture of my Blc. Copper Queen with the distinctly yellow petal/sepals/lip and said it was far more yellow than when it bloomed back in June. The reason given was because my porch/GH's are a lot cooler now than in the spring. That made perfectly good sense. Now the mystery.
Here are pictures of that "yellow" Copper Queen" and the sister plant that bloomed a few days ago. They were all photographed this AM. They are both divisions of the same "Mother" plant. The later-blooming sister plant has that coppery color, nothing like the other plant. Though they bloomed a few weeks apart, they both got the same light, temperature, fertilizer, water - in other words, their growing conditions were identical. Why the variation in color?
P. S. I am showing a couple of photos of each, with flash/natural light.
