I have a Nep. Spectabilis pangulobao up for trade. I have it around a year now and it just won't pitcher for me, 1 pitcher in that time. I heard they can be a little picky so maybe my windowsill just isn't working for it. It is the only Nep I have that won't pitcher. It's growing just fine, but just does not want to pitcher. It is currently in a 3" pot and could probably be repotted next year.
I am looking for a nice highland Truncata. My father has one and it is doing swimmingly on his windowsill. The spectabilis has more than doubled in size since I purchased it, so it is growing fast. I will post a pic of it tomorrow.
