About Saltmarsh sandspurry
Spergularia marina, commonly known as "Saltmarsh Sand Spurry," is a small annual or perennial herbaceous plant belonging to the Caryophyllaceae family. It is characterized by its fleshy, linear leaves and tiny pink or whitish flowers that emerge in summer. It is ideal for coastal gardens, saline rockeries, or as ground cover in high-salinity soils, where its resistance to these conditions makes it stand out.
Native range
Temperate and cold coasts of Europe, Asia, and North America
Care tips
This species thrives in full sun to partial shade, tolerating direct exposure well. It requires moderate watering, allowing the substrate to dry slightly between waterings, as it is sensitive to waterlogging. It prefers sandy, well-drained soils with some salinity, typical of its natural habitat. A common mistake to avoid is planting it in organic-rich soils with poor drainage, which can lead to root rot.
