About Matilija poppy
Romneya coulteri, commonly known as Matilija poppy or tree poppy, is a spectacular perennial plant from the poppy family, native to California and Mexico. It is characterized by its large, silky white flowers with a bright yellow center, which can reach 20 cm in diameter and emit a delicate fragrance. It's ideal for garden backdrops, sunny borders, or as a focal point in Mediterranean or xeriscape gardens, creating an impressive visual impact with its summer bloom.
Native range
California and Baja California
Care tips
It requires full sun and well-drained soil, preferably sandy or rocky, as it is very susceptible to waterlogging. Once established, it is extremely drought-tolerant and needs very little supplemental watering, only during very dry periods. Avoid transplanting it once rooted, as it does not tolerate root disturbance well, and this is a common mistake. Propagate by stolons or division in spring, but be aware that it can be invasive if conditions are favorable.
