Blue is a fairly rare color in nature (“Oh, yeah? Look up, numbskull.” — the Camera) but what blue there is tends to be very pretty. While these are blue berries, they are not blueberries. This is mile-a-minute weed (Persicaria perfoliata) or as our friend Lyla called it back in February, “Triangle-Headed Pokey Weed.”

Mile-a-minute vine, also known as devil’s tail and tearthumb, is an herbaceous annual vine in the buckwheat family. If you’ve ever encountered it you will know where the name tearthumb comes from. It is native to Asia but has become naturalized throughout the area and is a serious pest. Think of bindeed on steroids and with seriously barbed stems but without interesting flowers. It does have interesting fruit, I have to admit. These little berries are less that 5mm across but they are such a clear, beautiful blue, I cannot help but enjoy them. That’s not to say I would ever consider growing this for the ornamental value of the berries, of course. But they are still pretty.
