Euphorbia x martinii is a natural hybrid of Euphorbia characias and Euphorbia amygdaloides. It grows to around 90cm and like most of the genus likes a dryish soil in a sunny location. The attractive small flowers are composed of lime green bracts with wine-red nectar glands in the centre. It blooms from spring to early summer. As all spurges it produces irritating milky sap and the plants should be handled with caution.
