Hello (: This spring I planted some mint seeds in several small plasic pots put on my patio. When they started sprouting, I noticed there was one lone seedling that looked completely different in one pot - it had red stems and four almost sparkly, teardrop-shaped leaves. I left it alone because I wanted to see what it was. It started growing with the mint and then another popped up. This new one quickly died, but the first grew enough I planted it in a window box with two of the mint plants it had been sharing a pot with. It grew amazingly and the pictures attached are the plant at 4 months and another small seedling of the same type that's been around for about two weeks. The plant is 17" across at it's widest point, doesn't smell at all, and in the evening the leaves 'close up' and bunch together. The seed pods can be seen in the second picture - the seeds themselves are very small and black. Does anyone know what plant this could be? I've tried searching Google, but I haven't found anything... Any help at all would be appreciated.
