I need some help choosing plants for a tiny circular raised bed. It is about 1 metre in diameter and has a pole in the centre with a dovecote on top. It is in a sunny position all summer but probably half shade in winter. The main problem is we have chickens who like to scratch round in the beds looking for worms and usually destroy anything we put in there. The bed is absolutely covered in weeds and I don't really have the time to keep on top of it. So I would like something that provides good coverage to stop the weeds, strong enough to withstand the chickens and doesn't require much maintenence (so not asking for much)! A touch of winter colour would also be a bonus!!
Any ideas gratefully received!!
