What plant associations are you particularly pleased with in your garden? I'm loving from back to front, smoke bush + white potentilla + dark geranium phaeum + allium purple sensation + stachys at the front. Also a massive clump of bergenia with blue hardy geranium peeping over from behind, and crocosmia behind that. Especially good because the sun comes from behind it all, so the crocosmia foliage lights up. Yum.
And what do you struggle to find a fabulous friend for? I'm struggling with some aruncus. It behaves like it wants to be right up front, but at the same time is just too big! Grr!
