What special adaptations do spike rushes have?

Spike rushes, belonging to the genus Eleocharis, exhibit several special adaptations that enable them to thrive in wetland environments. Their slender, upright stems reduce drag from water currents, allowing them to maintain stability and access sunlight for photosynthesis. Additionally, their extensive root systems anchor them in soft substrates and help with nutrient absorption, while their ability to reproduce both sexually and asexually ensures resilience in fluctuating habitats. These adaptations collectively enable spike rushes to effectively colonize and stabilize marshy areas.
