Californian tree poppy, Romneya coulteri, is 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. You'll be rewarded with lots of "fried egg" blooms for many many weeks!
