Question about goldfish, and plants.

I was thinking, I've got some of those 'beta plants' (you know the ones that
come in those vases with beta's) laying around the house in glasses and
such, and I was wondering.. what if I made a section of my aquarium with
some of those sticking out of the top, and the roots in the water? Do you
think they would hurt the fish at all?

....I don't think anyone's ever tried it, but who knows..
