This is a highly architectural plant with evergreen foliage topped by a huge dome of bright golden-green flowers, which last for months. It revels in well-drained conditions, and like many euphorbias enjoys hot dry positions. It looks most at home in the company of other plants that enjoy dry sun, such as rosemary, ballota, and purple sage - its natural companions in a wild Mediterranean habitat. The plant also teams well with daffodils. Alternatively plant in groups to add drama to rock and gravel gardens. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
