Whereabouts are you? What summer and winter temperatures do you get?
Ah, I've just seen from earlier threads that you're in Yorkshire - I was wondering whether you might be in the US as they call their gardens 'yards', but you're talking about an English Back Yard
My front garden only gets sun in the afternoon (west facing). Some of the plants that are happy there are Clematis cirrhosa Freckles, Clematis viticella Etoile Violette, Sarcococca confusa, Salvia greggii, various hellebores, aquilegias, Hesperis Matronalis, Echinaceas and the lovely purple Aster frikartii monch. They're all really popular with the bees, butterflies, moths and hoverflies etc
