Anyone know what this plant is?

I got it at Target over the summer in a little grow kit, but I foolishly threw away the packaging and don't remember what species it is. This is the vine from the other day, BTW.

I'm not sure. I thought at first it was a morning glory but the petals aren't right. I'm trying to get a second opinion from a botanist friend of mine.
