WooWho! I repotted my ventricosa x xTrusmadiensis this evening because it was leaning over on one side and I was out of bark when I first got it. And noticed this...
Yes, that tiny little spec of green is a basal!
Here is the repotted plant, now with two growth points and a basal.
Here is the last pitcher. It hasn't produced one for me yet but I have only had it for a couple of months.
It is N. ventricosa x xTrusmadiensis (a) from EP in case you were wondering.
