Attack of the Gourd Plant

This spring when we planted our garden we decided that we were going to keep it simple. We pretty much planted a bunch of bulbs and a gourd plant....as well as some petunia's and marigolds to add a little color until the bulbs came up. Well look what happens when you plant 1 gourd plant, that according to the information on the stick that came stuck in the pot is only supposed to grow about 5 feet around.

Basically, this gourd plant has taken over our garden and is in the process of killing everything else in it. It is also trying to infiltrate our neighbors yard as well. I'm thinking this gourd plant is either pocessed or possibly on 'roids.
