Many months ago I bought two pots of multiple crowned cephs. They are still my most expensive CP purchase. When I first got them, one pot had a single mature pitcher. It was beautiful and it lasted a long time. Now the pots are mostly full of leaves with only a few tiny pitchers here and there. I have them growing in my kitchen windowsill. I would like to put them into a terrarium I'm setting up soon, but since I've read many times in this forum that changing a cephs growing conditions is a bad thing so I might just try one pot. I'm not really happy with the way my plants look on the windowsill so hopefully my plants will do better in a terrarium.
IMO, cephs are fairly easy to keep alive, it's harder to keep them healthy looking. I'd say Mexican Pings are the most likely CP to thrive in cultivation followed by Sundews. I've had bad luck with Bladderworts and VFT, which is weird and sad. I have not tried to grow Sarracenias, Heliamphoras, or Darlingtonias yet, but they do have the prettiest scientific names in CPdom.
