Thanks for letting me know. With the last leaf my plant is just over 30 cm in diameter, so it will be interesting to see how big the pitcher will be. Strangely on the leaf before that the pitcher was only about 5 cm, not anywhere close to the ones on your plant. Maybe the pitcher production is affected by my current growing conditions (cooler temps), or maybe it is just my clone.
Hrmm... well i do sometimes get warm daytime temps for my highlanders. Probably 26-30C, with a fairly nice drop at night at around 10-14C.
I have heard from an experienced grower that Burbidgeaes prefer to have their pitchers shaded from light in order to make large pitchers. Both the pitchers in my pics were inflated behind or in between pots, and out of direct light.
Hope this helps, good luck .
