Doug says that yes, it "should" be growing a lot taller and better. This tells me you're not growing it properly. Let me suggest you read the material on growing containers and sort it out. Unfortunately, I can't help you because I have no idea what soil you're using, how large the pot is, whether you feed or how you water. Read the articles here. Just about everything you need to know is there.
