Matilija poppy is a giant semishrubby perennial, spreading by rhizomes underground to form large colonies of thick, branched stems up to 10 feet tall. The selection 'White Cloud' is distinguished by its vigor, compact size (only to 6 feet), heavy flower production and huge flowers. Stems and leaves are bright bluish green in color. Clusters of white blossoms with golden centers, measuring up to 8 inches across, are carried at the shoot tips in summer. Their petals are broad and textured like crepe paper. Sun, well drained soil, moderate to no watering when established. When planting, take care to disturb the root ball as little as possible, as fine roots are easily injured and may not recover readily. Once established, invasive shoots should be pulled or spaded out from time to time.
