This one is growing pretty close to the weed in my previous post (Crazy Looking Weed #1), and it is most likely related to the other one, but it is different enough that it may be something totally different. This one is also growing in my flower bed that was previously part of one of our hay fields. I haven't found it elsewhere on the property.
The flowers are pink, and very small. At first, I was thinking Miner's Lettuce, but that plant has white flowers. But, it is very possible that it is Miner's Lettuce with pink flowers. There is no milky sap, so I don't think it is a spurge. I tore it in half, and there is a clear fluid. Also, there seems to be almost little to no root system.
Any help is appreciated!
