As far as I can tell the little plants we have growing outside the house are Alum. If anyone knows different please let me know. I'm pretty sure they aren't zucchini but I only did a quick mug shot search of other plants and can't be positive of it's identification.
Update: It's grown and I just never got around to editing the post. It turns out to be zebra hollyhock. I've added a picture (generic) of one of these below. So far it hasn't died and still puts off beautiful flowers in the spring and fall. It's gotten about 3 1/2 feet tall but not very wide.
