We're nearing the end of a mammoth garden redesign, and I'm hoping someone can offer a bit of inspiration on how to finish off a few small details.
The garden is now split level - the top level is a flat lawn, the lower level (about 5feet below) is a sunken patio. The retaining wall between the two is block and render with a built in bench.
My dilemma is how to screen/fence/edge/ finish off the top of the wall in order to prevent my two small children hurling themselves off the massive drop down onto the patio!
I dont really want to have to put a full fence up as it will make the patio feel like a bit of a bunker. Ideas so far have been to nick a bit of the lawn to create a flower bed (could be about 2feet wide) but i have no idea what to plant that would provide enough of a deterrent/barrier whilst still letting light through. Other suggestion is to build a sort of 'window box' along the top of the wall, but again, what to plant it with?
Any ideas/suggestions would be gratefully received!
