This is a stunning evocation of a Mediterranean landscape, with cork oaks, olive trees, and all the shrubs of a typical hillside. Go in early spring to see a Judas tree is startling pink, or in high summer to catch the aromatics rising off the cistus growing on the banks around King William's Temple. In winter the range of shapes, colours and textures of the evergreen foliage is a delight - silver-grey santolina contrasting with dark rosemary and bright myrtle. Just remember that in Kew it isn't always as hot as Crete!
