Known formally as Romneya coulteri, this perennial subshrub is from the Papaveraceae family. It is native to dry, sunny areas from California to Baja and has the largest flower of any poppy. Put in a warm, dry spot with plenty of room to spread. Flowers bloom late March until August and are great for attracting bees. It is not the easiest to get started with this variety but it spreads fast once established. It is known as a “fire follower” because it’s often found in burned areas in the wild.
