Romneya coulteri
Matilija Poppy
Description
Crowned by white poppies, this high-impact, spreading, gray green perennial stands statuesque at 8' tall. It is best used where its scale and habit will not overpower neighboring plants. It requires no summer water and thrives on dry alluvial slopes.
Maintenance Tips
Romneya coulteri is a large, herbaceous, California native perennial that is grown for its attractive gray-green foliage and showy, white poppy flowers that bear resemblance to fried eggs. It can grow up to about 8' tall and wide but can spread up to 20’ away by underground runners known as rhizomes. Despite its large size, it is relatively easy to maintain. Flowering begins in the spring and lasts until late summer. In the fall, the foliage will start to wither, which is when it is best to cut all the stalks down to about 6". Once they are removed, you can leave this plant alone to regrow back in a matter of a couple of months.
