Nepenthes and frogs, good or bad mix?

[Avacado]

I could be wrong, but that looks more like the hybrid N. 'Miranda'. To my eyes at least. Most N. ventricosa I've seen have squatter pitchers. I have a Miranda outside in my plastic "greenhouse" ... not rare by any means, but one of my hardiest and most attractive Neps. Anyway, nice plant!

I think you totally hit the nail on the head. Miranda is crossed with Maxima which I think this plant definitely has.
