I think it will look spectacular! Beautiful colour combinations. I so miss the Hellebores, it is far too hot to grow them here unfortunately. And delphiniums and many others. I wasted a fortune planting lots of English perennial plants here when we first bought the farm. Are you allowed to grow the lovely big pink Alliums, we are not. But wouldn't a few of those look wonderful in your new planting project?
I also at one time yearned far a small white garden aka Gertrude Jekyll. Must get back to catching up on some chores. Take care. Jo Jo
