Rosa spithamea, commonly known as the ground rose or coast ground rose, is a deciduous shrub native to the coastal regions of Oregon and California. It thrives in a variety of habitats, including open woodlands, forest edges, and chaparral areas, often in regions that have experienced recent fires. This species is particularly adapted to the Mediterranean climate found along the Pacific Coast. Rosa spithamea typically grows to about half a meter in height and is characterized by its prickly stems, pinnate leaves with toothed margins, and showy pink flowers that bloom in the spring and summer. The flowers give way to scarlet rose hips that are both ornamental and a food source for wildlife.

The ground rose is valued for its low-growing habit and resilience, making it suitable for use as ground cover or in native plant gardens. It is also used for erosion control on slopes and in restoration projects. In cultivation, it prefers full sun to part shade, well-drained soils, and moderate water, reflecting its native habitat conditions. While it is relatively low-maintenance, it may require occasional pruning to maintain its shape and to remove dead or diseased wood.CC BY-SA 4.0
