I have 2 pitcher plants in a single pot. The N. Alata sprouted around July (totally accidental, thought it was just a new stem since my ventrata has been in a bending position ever since I got it last May). My N. Alata (I assume it is alata since it has hairs on the pitcher) already has traps and is growing just fine.
On the other hand, My N. Ventrata hasn't been pitchering since then. It just continues to grow leaves with red tendrils (I trimmed the last pitcher it had since it was rotting, it was already grown when I got it) but the pitcher tendrils just dry off after a week or so.
The temperature here in the Philippines is 27C-32C (80F-90F). It rains about 2-4 times a week (rainy season). As you can see in the pictures it is placed on a rusty metal roof (heat/temp issues?). But as I recall I had a leaf that was just in the rim of the pot and it still dried off and another that didn't touch the roof and it still dried.
