Months ago, I planted 10 mangosteen seeds in pots at the same time I planted 10 soursops and 10 goji berries. Nothing came up until about a month ago, which was this plant pictured. The same plant is growing in the other pots that I planted mangosteens in, but somehow, I think this might be a weed. I was going to put it into a big container, but today there is a little yellow flower on it. If you can see in the picture, there is a thin stalk on the side. I couldn't get the picture of the flower in it though, but it is yellow. So, I am kind of disappointed that it looks like a weed, but I could be wrong.
