One tall conifer at the corner of each house. The object of this uniformity is to create a parklike vista of unblemished lawn to unify the neighborhood. The very idea of planting a dooryard garden in unthinkable. Erecting a decorative fence and planting beds to frame the grass would be perceived as an act of hostility. Good fences do not make good neighbors when they pop up in the front yard.
Gardens intrude on the unrelieved tranquillity of green.
No matter that the fenced yard with its charming cottage garden is a thing of beauty. It ruins the vista. It shouts to the world the message that this lone maverick has rejected the norms of the community. What the community demands is a perfect facade . Feel free to dream, as long as it's the same dream your neighbors have.
