I once saw in our old neighborhood in California a person had planted a flowering plant, A variety of hibiscus I think in a row they had clipped and tied the branches as they grew weaving them in and out tying them together and wiring to train, it indeed was a living fence with blooms very pretty and only about a foot and a half wide. Person also had bonsai trees in the yard. But if someone puts a planting so close to the line they can't keep it trimmed without going into the neighbors yard so without them being onboard it would I think be asking for a mess.
