Beth Chatto's Gravel Garden. This is a very English garden, despite the generally desert-like conditions. Yes, there are grasses and euphorbia but also: the dark sedum 'Ruby Glow', Nepeta, common chive, and Lamb's Ears. - (Euphorbia 'Blue Haze' is £6.99 from Larch Cottage Nurseries). Ordinary plants put together by an artist.
