I've tried growing darlintonia in clay pots a number of
times and have had only adequate "success". One problem
is that you may have salt buildup in the pot and so should
repot every season or two. Most people I've seen that have
had good success have used larger than average pots, which
probably help in temp control, and a couple have had success
with the peat pots which give lots of evaporative cooling.
I'm not convinced that there is so much value in the
evaporateive cooling as there is in minimizing the static
heat buildup in plastic pots. The greatest success I've
had was in a steamy, and warm, terrarium under lights, but
the pitchers were not strong enough to stand much movement.
My dream is to have enough space that I could plant D. in
a ball of moss and put it in one of those garden waterfalls...
