Okay, so all the N. 'Effulgent Koto' pitchers I've seen have stripes on the peristome. However, mine hasn't made a single striped peristome pitcher. So I just figured they'll get their stripes when they get bigger. Well, they're getting pretty big and still no stripes. I have two of these plants, and the smaller one is now working on it's first pitcher. I have to say I'm noticing a little difference in pitcher traits.
Here's the pitchers being produced by the larger plant. Uppers, or no?
Now here's an upcoming pitcher on each plant. The one on the left is the larger plant's pitcher, and the one on the right is the smaller plant's. Kind of makes me wonder..
I think the only way to know for sure without professional opinions is by waiting for this new pitcher to open. If the first pitcher on the smaller plant is striped, well.. mystery solved.
