Romneya coulteri - Matilija Poppy
Pot Size: Quart, 3-Gallon, 5-Gallon
The Matilija Poppy is often found in areas of California with dry canyons or coastal sage scrub. Famous for large showy flowers, this shrub will grow large (6-10 feet tall, 20 feet wide) and needs annual hard pruning to manage the size. Woody stems grow prolifically from rhizomes. The large flowers have six wrinkly white petals that surround a bright yellow cluster of stamens (the colors have earned its comparison to a fried egg). It was nominated for the California state flower in 1890, but lost out to the CA poppy. Patience is required to establish this plant, as it's summer deciduous and winter dormant. Once established, pull shoots to effectively control aggressive spreading.
Plant Type: Perennial herb shrub, CA Native
Size: 6-10' tall; up to 20' wide
Light: Full sun
Soil: Prefers sandy/gravelly soil with fast drainage
Water: NEVER irrigate once established!
Bloom: White/ yellow flowers in spring and summer
Other Notes and Uses: Matilija poppy shrubs are deer resistant. Because of their eventual size, they are excellent for large spaces with low maintenance needs. Particularly attractive to bees and butterflies, this CA native makes a showy, eye-catching statement for a large garden area.
