It seems like this would be a good way to start a hedge of roses--and I wonder if you could being a hedge of osage orange by the same process. Osage orange makes a stout wall to keep livestock in and intruders out. The traditonal method of starting a osage orange hedge involves all the ditch digging and then grinding up lots of hedge apples and making a slurry of seeds and pulp. Then each year's growth is woven together to create a solid hedgerow.
A rose wall probably wouldn't be as impenetrable, but heirloom roses could be cultivated for aromatherapy and for rose hips.
