This summer I found a unknown plant growing in the front yard. I left it, but I can't recall if I had it last year. I thought it looked like some sort of hydrangea, so I figured to leave it.
Later on I noticed that it had flowered (unfortunately no picture of that). And now, I went out there and it has berries where there were once flowers.
Here some photos:
It had pink/red stems that are pretty thick. Is it a good plant or a weed?
