Transformer station flower beds - update

Four of us (Mike, Joey, Darren and Mary) got together yesterday evening to transport limestone from Mike's secret spot to the front of the transformer station. The new flower beds there are starting to look good! We still need to level-out the soil and spread some mulch, which we can hopefully get done over the coming days. As for the path, can I suggest perhaps a few low hedges (spirea?) to be planted along its edges, perhaps with mulch forming the path itself? I don't think we would need to do the entire length of the path leading to the street, maybe just a 3rd of the way down to give it a suitable 'look'?
