The OP did say "I want to create a natural barrier of sorts between the two driveways without entering into any border disputes", so we should assume that the troughs will be on his property.
I think, as a new home owner, you probably have plenty of other jobs you could get on with in the house and garden where you know your time and money will be well spent and will anhance your home and its value.
I think curb appeal projects almong a common boundary are best left until new owers/occupiers turn up and you can get to know them a bit before springing a project on them. Assuming they're reasonable and you get along OK, you could then discuss some sort of solution but, as I said, to maintain decent plants in good health and looks you'll need something quite substantial as planters and you'll need lots of very good compost to grow them in and that doesn't come cheap. Then you have the cost of plants on top so it's going to be a fair financial undertaking plus all the maintenance to keep them looking good.
Vendée - 20kms from Atlantic coast.

Just to say i have successfully grown 6 foot bamboos in both pots and troughs, creating a living but portable barrier. Need watering occasionally, but never fed them - seemed indestructible.
Not getting in to the rights and wrongs of border disputes ( don't know enough to comment) , but as a planting solution it might work
i actually thought Bob would place the containers on his side of the border why wouldn't he then he has no problems with anyone in making it all look much better
i wish mine would just cut the hedge a bit more often but then im off so dont care anymore now cant move fast enough
