A couple of weeks ago I bought some fancy grass (blue fescue, Festuca glauca) for a planter that was going to cover something up. (Okay, cover up an access to the septic tank. Important to put Something Pretty over it.)
I figured I’d add something for contrast later, but haven’t gotten around to it so far. But no worries, nature did it for me, depositing a leaf from the ornamental plum in Just the Right Spot.
