Romneya coulteri is spectacular low growing shrub. It produces beautiful white and off-white flowers with a fragrant aroma. These flowers are attractive to butterflies and hummingbirds, making Matilija Poppies ideal for gardeners who wish to attract wildlife to their gardens.

Matilija Poppies are great for adding texture and color to gardens situated near the seaside. They are considered moderately salt tolerant, so they can also be grown near coastal regions with salt spray.

These spectacular shrubs are native to California and Mexico, and can be grown in USDA Zones 7 to 11.

If you are looking for a reliable, drought-tolerant shrub that will brighten up your garden, Matilija Poppies are a great choice. They prefer to be planted where they have well-draining soil that is kept moist. It is important to avoid overwatering, as this can cause root rot, and avoid over-fertilizing as this can produce too much top growth and make the plant look spindly. With plenty of sun, adequate water and the right soil, Matilija Poppy will make an eye-catching addition to any garden.
