Most of what I find particularly attractive in my garden has happened purely by accident.
This is a classic example. Our flowering evergreen Clematis armandii has crept down in amongst the leaves of what I now think could be an Euonymus (thank you Molly), and looks stunning.
As you can see (below), all this happens around the pump house door, where I visit fairly regularly at the moment to check on the mouse situation. A couple of years back I found that, over winter, bloody mice had chewed all the electrical wires in the control box, and (when it was opened-up in June) the pool's circulatory system refused to operate.
This year I'm keeping the little blighters in check, with mousetrap and cheese, whilst enjoying these fabulous flowers. Evergreen, creeper, and fabulous flowers; can't be bad, can it!
