Coulter's Matilija Poppy
Romneya coulteri

Romneya coulteri holds the record for having the largest flowers of any plant native to California. Each flower spreads out like an egg cracked into a frying pan. The six crinkled white petals surround the sunny-side-up yellow center of multiple stamens. The extraordinary flower and imposing habit of this poppy have made it a prized garden ornamental in California and other parts of the world. Once established, its creeping underground rhizomes give rise to a vigorous colony that can spread well beyond the parent plant.

DISTRIBUTION: Dry washes and canyons from the eastern South Coast to the Peninsular Ranges; < 1200 m.
