I'm a big fan of Hydrangea paniculata 'Tardiva' – it's right up there with the oakleaf. This one's pruned to be almost espaliered, wide but close up against the English laurel hedge. So in this tight-fit border I can still walk along the middle, passing between the Tardiva and that 'Ogon' spirea. Speaking of which, I'm in love with its chartreuse willow-like foliage anywhere, but especially with the lamb's ear. There's some Salvia 'May Night' and reblooming Tradescantia in this vignette, too.
For once, I followed the Garden Blogger Bloom Day rules. Though back on my blog I broke 'em again.
