Sobre coloração de Pings e outras PCs, leiam abaixo comentário do Andreas Fleischmann postado no CPUK (

"... the colour of the scapes and also the flowers is more intense at natural habitats, because the plants get higher levels of radiation there, in combination with a notable temperature decrease at night (which is usually not given in cultivation). That's why the scapes are dark reddish in the wild, but usually remain green in cultivation. [for those interested [off topic]: the red pigmentation of most CPs is caused by anthocyanines, which accumulate like sugars in the cells of the plant. The more difference between day temperature and night temps, the more sugars and pigments are found in the cells, and the deeper coloured they will get. This is because the plant cannot consume all sugar produced during the day at night (as the nocturnal sugar metabolism is temperature dependant - the cooler the nights, the less the plant can consume; some alpine plants are adapted to this, that's why they do not grow well at low altitudes: they starve! That's why some high alpine plants like Nepenthes villosa are so difficult to grow when they do not get a propper nocturnal cooling). And the same is the reason why your venus flytrap will get very dark red leaf blades in autumn. However in case of the reddened scapes of these Genlisea, this is nothing essential for the plant - they may look better with red scapes, but actually this is protection of the plant against radiation, and they will do as well without this red colour]."
