My biggest is Nepenthes X dyeriana which is over 4 foot tall, 3 foot wide and has some leaves over 19" excluding the tendril. Mind you, the growing stalks are tied to orchid sticks to keep it at 3 foot in diameter. The biggest pitchers are over 12" or a foot and that excludes the lid. Only the bottom of the pitcher to the top of the peristome. In fact, it got so top heavy that it fell over and landed on my bed while I was sleeping in the middle of the night! That was not pleasant since i had to repot that guy the next day. Thank god only minor damage to the plant. I plan to let it grow to the ceiling of my bedroom and put a trellis on the ceiling to let it vine and hang down! And besides that, it's a killer Nepenthes. You can see it on Peter D'Amato's book the Savage Gardern or at my website http://www.venturalink.net/~maxxpaxx...thesathome.htm and go to the photos section. The pitchers are gorgeous.
