My N. rokko 'exotica' is a girl! YES! Here are the 'technical' details:
Time to opening: 2.5 - 3.5 weeks
Lenght of stalk: Short
Lenght of vine: 1.5 feet
Source: Exotica Plants
Condition of plant: Healthy, normally pitchering
The last pitchers I got on this one was about a month back. My maid forgot to water it for 5 days and I came home to find the growing tip touching the ground. Thank goodness for the high sphagnum media, I still wonder how it survived in that basket. But fine now, more pitchers coming along.
