Romneya Coulteri Matilija Poppy (5 Gallon)

About this item

Make a dramatic statement in your garden with the California Tree Poppy, also known as the Matilija Poppy or the beloved “Fried Egg Flower.” This spectacular California native perennial is famous for its enormous white blossoms, which can reach 8–9 inches across. Each flower features delicate, crinkled, crepe-paper-like petals surrounding a prominent golden-yellow center, creating an unforgettable display from late spring through summer. The blooms also offer a subtle, apricot-like fragrance.

Growing 6–10 feet tall, this woody-based perennial features attractive blue-gray to grayish-green foliage and an upright, shrub-like form. It spreads through underground rhizomes, gradually forming impressive colonies when given room to grow. A natural fit for dry gardens, native landscapes, and spacious planting areas, the Matilija Poppy brings bold texture and exceptional floral impact.

For best results, plant in full sun and lean, fast-draining soil, such as sandy, rocky, or gravelly ground. Once established, this drought-tolerant native requires very little water and performs best without summer irrigation. It can be challenging to establish and dislikes root disturbance, so choose its permanent planting location carefully. Cut back old stems near ground level in late fall or winter after flowering.
