Needle spike rush is a perennial aquatic plant that belongs to the Cyperaceae family and the Eleocharis genus. It is scientifically known as Eleocharis acicularis. This species is commonly found in wetland habitats throughout North America, Europe, and Asia. It is characterized by its slender, needle-like stems, which can reach heights of up to 30 centimeters.
The needle spike rush has a distinctive appearance, featuring clusters of thin, cylindrical stems that emerge from a fibrous root system. Its stems are light green in color and have a smooth, hairless texture. The plant produces small flowers that are often inconspicuous and can be easily overlooked. These flowers give rise to small, rounded fruits that contain a single seed.
This species is typically found in shallow water bodies such as ponds, marshes, and slow-moving streams. It thrives in both acidic and alkaline conditions, and it tolerates a wide range of water depths. Needle spike rush serves as an essential component of wetland ecosystems, providing important habitat and food sources for various aquatic organisms, including insects, fish, and waterfowl.
Due to its attractive appearance and ability to adapt to different water conditions, needle spike rush is also popular in the aquarium trade. It is often used as a decorative plant in freshwater aquariums, providing a natural and visually appealing setting for aquatic animals.
