Another Mystery Plant

Another Mystery Plant

I'm sure everyone gets tired of people asking to identify plants for them, but I'm very new to all of this and I must bow to the superior knowledge of the people in this community and beg for help like the gardening newbie I am and hope that you'll forgive my cluelessness. I know it's a very common plant, as I've seen it before in other peoples' gardens, but I didn't plant it and have never had it in my garden before, so I don't know what it is. Thank you!
