I bought a trio of red VFT's in one 2" pot from Home Depot last August. I successfully brought them through dormancy and two of the three are rewarding me with a flower stalk. They went from being very red to looking mostly green, afetr dormancy. After a few weeks of gradually warming them up, I put them outside for sun and photosynthesis. It has been two months now and the although the new leaves and traps are twice the size of what they were last Fall, their traps are still green. Inside the trap it is reddish. Why aren't the traps turning red?
