Romneya coulteri | Tree Poppy

Romneya coulteri, also called the Tree Poppy or Matilija Poppy, is one of California’s most iconic native plants, celebrated for its spectacular blooms. The massive white petals have a crepe-paper texture and surround a bold golden center, with each flower reaching up to 8 inches across. From late spring through summer, these blooms create a striking display above tall, silvery-green foliage. This vigorous perennial spreads quickly, making it a standout choice for large borders, dry slopes, or native landscapes.
