Hellstrip Gardening

I'm not sure if this exactly qualifies as a hell strip, but given that: (1) we don't have a sidewalk, (2) this area abuts the street, and (3) it also marks the path to hell (the devil garden), perhaps it might. This is a row of 5 to 6 foot tall foxgloves that run about 20 feet down the line between my asphalt driveway and the gravel area to the side. Amazingly, these are volunteers; they started growing a few years ago and come back every year now with no effort on my part other than a quick shake before cutting the spent stalks. They seem to just love the little gap between the weedcloth underlying the gravel and the driveway.
