A compact shade-loving Euphorbia that has long-lasting acid-yellow flowers in spring that contrast beautifully with the deep purple strappy foliage strung in whorls around stiff stems. Try it towards the front of a border where its foliage can be appreciated or as a groundcover for a difficult shady site among spring-flowering bulbs such as Narcissi. In a small garden it may need checking since it self-seeds freely.

• Garden care: In autumn cut back the faded flower stems avoiding new ones on which next year's flowers will appear. When working with spurges always wear gloves since the milky sap is poisonous and a potential skin irritant. Remove unwanted seedlings each spring as part of routine border maintenance.
