You don’t have to be a fan of California natives to recognize the Californian tree poppy! Many instantly fall in love with its enormous “fried egg” flowers of pure-white petals the texture of crepe paper which appear for months on end in the summer. Together with its handsome, deeply lobed, grey-green leaves they make Romneya coulteri an excellent specimen plant for a sunny mixed border. Just be aware that this handsome plant is one of the tallest members of the poppy family as well as having the largest flower in the genus!

While the plants can prove tricky to get going as they resent transplanting, once established they will spread readily. The Californian tree poppy requires fertile, well-drained soil, and shelter from strong winds. It can be propagated from root cuttings taken in the winter-early spring months.
