Euphorbia marginata

This makes a branching plant with large grey green smooth looking leaves on upright stems. Near the top of the stem the leaves develop some white variegation and sometimes the white will predominate. In late summer it flowers. What appear to be petals (in fact bracts) are variegated, pale green and white: the tiny greenish object at the centre is the true flower. The whole effect is cool looking but classy. Give this plant a sunny site in any reasonable soil that is well drained. It makes a lovely foil for all the bright summer flowers. As with most euphorbias, the sap is poisonous and can irritate the skin, so wear gloves when you tend them. The plant can reach up to 90cm (3ft) in height, often less, with a 50cm (20in) spread.
