ROMNEYA coulteri. Southern California. Matilija poppy. A giant semishrubby perennial, spreading by rhizomes underground to form large colonies of thick, branched stems up to 10' tall. Both these and the divided, toothed 2-6" leaves are bright bluish green in color. Clusters of white blossoms with golden centers, measuring up to 8" across, are carried at the shoot tips in summer. Their petals are broad and textured like crepe paper. We offer material of two clonal selections: ‘White Cloud’, is distinguished by its vigor, heavy flower production and huge flowers. ‘Butterfly’, our own selection, is a more profusely branched plant. Its smaller flowers have round, overlapping petals. Sun, well drained soil, moderate to no watering when established. Invasive shoots should be pulled or spaded out from time to time. Hardy to 5-10oF.
