So, I have come upon a strange plant that I bought from the graveyard at Lowe's for .75 cents. I have NO idea what it is, and cannot find a picture, description, etc anywhere. So help if you can- it has an upright growth habit, the teardrop shaped leaves start out a kind of bright green, and as they get bigger they turn a deep red, and it grows FAST. I left for vacation for almost 3 weeks and it grew about a foot and a half. It seems to like the west-northwest facing window I have it on. And no, it's not a sweet potato vine, as my wife likes to argue at every chance she gets. I can't place it, have never seen anything else like it, and I just want a name to put to the face. Or non-face... however you wish to look at it. Please help!!
