Ideas for low maintenance screening plants in a coastal garden border

[Tryingtobegreenfingered]

I’m looking for some inspiration for a tricky patch of garden. It’s seafront and runs along the border of a fairly tiny patch of garden. I’m trying to screen off the neighbours wheelie bins but can’t have anything too high. Something Evergreen would be good, although not essential. Nothing too formal as it’s quite a relaxed seaside cottage garden. The thing that makes it a bit trickier is dogs pee there, I think! Oh, and as little upkeep as possible, please!

Any ideas? There were a few things originally planted but they’ve not done very well and now it’s just full of weeds.

How about a tall ornamental grass? There are loads of lovely ones, it would work well with the seaside vibe, v low maintenance and tough

Escallonia or griselinia. Both are great in coastal salty air.

Euonymus Japonicus Green Spire.
A small, narrow bushy, evergreen shrub that grows to 0.5 to 1m tall, so minimal maintenance.
It can be used for hedging, planting 3 to 5 plants per metre depending on plant size at purchase. It stays in a neat column so won't overspill into your neighbour's garden.
It's a tough shrub that copes well in coastal areas.
