About Sea rush
Juncus maritimus, commonly known as Sea Rush, is a perennial plant native to coastal and saline areas, valued for its resilience and upright growth habit. Its cylindrical, blue-green stems form dense clumps, adding interesting architectural texture to coastal-inspired gardens or wetlands. It is ideal for stabilizing saline soils and creating a natural ambiance around ponds or brackish water areas.
Native range
Temperate and subtropical coasts of both hemispheres
Care tips
Sea Rush thrives in full sun to partial shade, tolerating a wide range of light conditions. It requires consistently moist or even inundated soils and is highly tolerant of salinity, so watering should be frequent if not in an aquatic environment. It prefers clay or silty substrates rich in organic matter. Avoid allowing the substrate to dry out completely, as it is a moisture-loving plant and could become stressed.
