With the recent milder weather, I took these pics of my Darlingtonia. The plant grows under T12s in an unheated room in my basement & it was just starting to break dormancy. Since there was some unsightly surface moss, so I decided to repot the plant in fresh 1:1 NZ LFS: coarse orchid perlite. One week later, here's what the plant looked like. Instant red! ;D Perhaps the extra nutrients in the new mix was the culprit as there were no other changes to its growing conditions. Good growing Rob

Thanks Doug & wonderful insight on a potential root cause! In fact, I would have to agree with you after reading the article. The old mix may have been on the basic side, as evidenced by the patches of common moss seen growing in the pics. After repotting, the fresh sphagnum probably tipped the soil pH to the acidic side, protonating those anthocyanin pigment molecules. And, voila, red Darlingtoniia! Totally makes sense. Now I can't wait to see for the pH to transition up & result in purple cobras ;D Great growing, Rob
