If its growing in a pot, it may have run out of room. Otherwise, I would guess that its putting more energy into overall pitcher production than it is into pitcher size. But yes, it is a very, very prolific hybrid. I was going to divide mine this past spring, but had such a hard time finding all the growth points amongst all the pitchers, with my miniscule patience, I gave up. I'm going to have to do it this next spring though, it's smothering the neighboring plants.
