The Matilija poppy or tree poppy (Romneya Harvey) is a poppy of Southern California and Northern Mexico, belonging to the poppy family (Papaveraceae).
They are perennial subshrub with a woody stem. They may grow to a height of 2.5 meters (8 ft) and a width of 1 m (35 in), with the flowers up to 13 cm (5 in) across. The silvery green leaves are deeply cut, with a small fringe of hairs at the margin.
They are notable for their large white flowers with intense yellow centers, blooming in summer. These flowers prefer a warm, sunny spot and fertile soil with good water drainage. They are not easily grown, and also difficult to remove.
