In Southern California, R. coulteri grows best in sandy, well-drained soils.  It dislikes summer water and for that reason does poorly near lawns.  Home gardens that are not willing to forego summer watering should avoid this plant.  However, if it does not get summer water and is left to grow in a well-drained soil, it can become quite happy, almost invasive as it spreads by underground runners.  If not overwatered, R. coulteri an survive in even heavy soil, but will not be as effusive.  For a plant that can be exuberant as the Matillija Poppy, this is not necessarily a bad thing.
