The Romneya is beyond doubt the finest of all wild flowers, none of the newly introduced varieties of the Poppy family being equal to this wonderful native flowering shrub. Every garden, unless extremely small, should have its plant of Matilija Poppy. The Romneya Coulteri thrives in any soil (provided it is well drained) and requires no artificial irrigation, but it must have a sheltered, sunny exposure in order to perfect its large and beautiful Peony-like white flowers.
This Poppy is propagated by seeds sown in a warm frame during early Spring, sandy leaf-mold being used and the seeds being covered to the depth of a quarter of an inch. It may also be propagated at the same season by division of the roots.
