i dont know if my plant will get much bigger but this is my biggest one i have ever owned and the leaves are about four to five inches long and the traps range from one to 1 1/2 inches long and they are about three to four centimeters in diameter it has about seven traps right now and a foot long flower stalk.
unless you are planning on growing seed, clip the flower stalk, it is robbing your plant of energy.
Once the stalk is clipped, your plant will probably put out even larger traps.
I believe the average for "LARGE" traps, is 2 inches, there are some 'cultivars' out there that claim to have larger traps than that.
Any how, remember, unless you are planning on growing seed then that flower stalk is really ripping your plant off, stealing energy left and right, and it DOES effect the size of your traps! clip that sucker!
