Never mind a gnome, no other garden at this year’s Chelsea flower show can boast a Barbara Hepworth sculpture like the RHS gold-award-winning Tate Britain garden. And few will have such a significant afterlife. Designed by the landscape architect Tom Stuart-Smith, it is a microcosm of a major redesign for the gallery’s Millbank garden, opening next spring.
