About Common spike-rush
Eleocharis palustris, known as common spikerush or creeping spikerush, is a perennial aquatic plant forming dense tussocks of slender, cylindrical stems, with no visible leaves, emerging directly from the rhizome. Its delicate and upright appearance makes it ideal for pond edges, artificial wetlands, or as a background plant in natural-style aquariums, adding a fine texture and vibrant green color.
Native range
Nearly cosmopolitan in temperate and boreal regions of the Northern Hemisphere, including Europe, Asia, and North America.
Care tips
It requires full sun to partial shade and a consistently moist or submerged substrate in a few centimeters of water, preferably rich in organic matter. It is essential to maintain a good water level to prevent the substrate from drying out, as it does not tolerate drought. It is not demanding regarding fertilization, but a light nutrient application in spring can promote its growth. A common mistake is planting it in dry soils or with low humidity, which leads to its rapid decline.
