Romneya coulteri, also known as Coulter's Matilija Poppy or California tree poppy, is a beautiful perennial flowering plant native to southern California and Baja California. It grows in dry canyons in chaparral and coastal sage scrub plant communities, sometimes in areas recently burned. This shrub can reach up to 2 m in height, with gray-green, waxy leaves and large, solitary white flowers with yellow stamens. It is a popular ornamental plant, prized for its showy flowers. However, it should be planted with caution as it can grow aggressively by spreading underground rhizomes. Romneya coulteri bears the largest flowers of any species native to California, surpassed only by Hibiscus lasiocarpos. This magnificent plant was nominated for the honor of California state flower in 1890, but lost to the California poppy. Experience the beauty of Romneya coulteri yourself by planting it in your garden!
