George,
I can't say I have ever seen a VFT with three inch long traps (do you
live near a nuclear power plant!?) , but I have heard about a Venus fly
trap with 2 traps on on leaf. It was at an ACPS meeting quite long
ago, and I think it resumed producing the normal one trap per leaf
after a couple of months. This one though produced *ALL* leaves with
two traps!
Seeya,
