Cindy, read the pinned topic you started (VFT Tanning--I pinned it.) It may hold the answer you seek. I have found some VFT's are grown in very bright shade (whitewashed greenhouses), and the plant had the genetic set that allowed it to color up in bright light conditions. I have taken plants grown in this way, put them in full sun, and watch the color wash right out in any new traps that develop. Full sun was not what they were looking for, but the bright shade they had such beautiful color in. Thier genetics caused them to color up in bright shade, not full sun. Many of the most colorful traps I have ever found in the field were growing in filtered light through the grasses growing over them. How many times I have heard, "My VFT's lost their color! WHY!?!?!?!?!?!", I cannot even tell you. But, not all the plants respond to direct, full sun, while others will. Read the pinned topic.
