I think it must have been hidden amongst the other shrubs last year. Plus, it's in our woodland garden where its quiet and shady. We tend not to venture in there very much. You never know what's lurking in the woodpile.
It sounds grander than it is, pasta. It's a shady are of the garden which has been planted with shrubs and flowers that like shady places. The birds and the hedgehogs love it, as do I.
As well as that lovely Clematis, I can see some hawthorn and some nice Ceanothus too.
My 2 ceanothus are in full bloom right now, great low maintenance shrubs!
