Groundcover under blackthorn
I've just cleared the stinging nettles, old plastic trays and bits of buried bamboo cane the previous owners seemed to like to use to underplant things from beneath a small blackthorn bush.
I need something to keep the weeds down. Especially as weeding under the blackthorn is a prickly unpleased business. Any ideas for an evergreen groundcover plant?
It'll be a sunny-ish spot (aside from the blackthorn) and relatively sheltered, though we are in County Durham on a hill so needs to be hardy.
