About Sand sedge
Carex arenaria, commonly known as sand sedge or sandstarr, is a rhizomatous perennial grass native to the sandy coasts of Europe. It is characterized by its fine, arching grayish-green leaves and its ability to form dense clumps, making it ideal for stabilizing dunes, ground cover in coastal gardens, or as a low-maintenance ornamental plant in rock gardens.
Native range
Coasts of Western Europe
Care tips
It prefers full sun to partial shade and sandy, well-drained, preferably poor soils, tolerating salinity. Watering should be moderate once established, as it is very drought-tolerant; overwatering can be detrimental. A well-draining substrate is crucial to prevent root rot. Avoid planting it in heavy, clayey soils, as this can lead to its decline.
