Simple-But-Cute Mailbox Flower Bed

I've recently gotten back into taking ~2 mile walks/jogs around our neighborhood a few evenings a week, just to stretch my legs, but not do anything too strenuous in the heat of summer. And while on one of my jaunts around the neighborhood, I was inspired by a neighbor's simple-but-cute mailbox flower bed. So I made my own in our yard!
