  A stunning, late-flowering semi-evergreen euphorbia with open sprays of intense, lime green flowers held on red-bronze stems in late summer to early autumn. The foliage is handsome, too, with strappy, grey-green leaves held in whorls on the upright stems. This magnificent perennial forms a natural mound, bringing all-year structure to the garden. In the fading autumn light, it glows and looks fabulous among late-flowering perennials and grasses, or with spiky plants. It is drought tolerant once established.
  
  
• Garden care: After flowering remove the faded flower-heads. When working with spurges always wear gloves since the milky sap is poisonous and a potential skin irritant. Euphorbias do not like waterlogged soil.
