Romneya Coulteri

Although it dies down in winter, this substantial gem creates a shrub-like effect in summer, with many upright, branching stems clothed in leathery, silver-grey glaucous leaves. These are topped with fat buds, which open into spectacular poppy-like flowers with golden-yellow centres, and crumpled tissue-paper-like petals pinned together with the mass of yellow stamens. It thrives best in a warm, sunny sheltered position.
