ID of grass seedling
I'm hoping someone here might be able to ID this grass that came up in my flower bed. It's a pretty grass, which is why I left it - but now I'm starting to fear it might be something I don't want going to seed. It's about a foot tall, and has soft foliage, but the bloom stalks are reed like. I tried to take some pics but it's harder than I would have thought to capture detail of grass in a picture. I'm actually not as interested in a specific ID of the grass as I am concerned about the type of plant and whether or not it is some invasive weed. Thanks in advance if anyone can help.
