So about 3 weeks ago I decided to get off of my teen butt and start doing something productive, like planting. I decided to buy a pack of California Wonder 300 TMR Bell peppers, my parents love 'em. Prepared a lot in the backyard, threw some seed in there, and waited. A week after, I was surprised by two leaves coming out of the ground; and by the second week the plant was already right along 5 inches tall. But that was the only plant with the first true leaves and then some, the others where barley coming out yet. So I googled again, and tada, obviously not a bell pepper plant. Its a vine, since its sticking to a fence behind it, but now I'm even more confused. The leaves look somewhat like those of a grape vine, although I highly doubt its a grape. But then... what if it is? Or some other delicious fruit? So, should I just take it out? Right now its about 10 inches tall and growing, with 2 bell peppers plant getting overshadowed by it. Can you guys please help me identify it?
tl;dr Not the plant I wanted, but do I keep it?
