Eleocharis acuta

Eleocharis acuta, or Common Spike-rush, is a slender, spreading perennial sedge in the family Cyperaceae, native to Australia. This semi-aquatic species is commonly found in wetlands, shallow water bodies, and along riparian zones, where it contributes to the ecological health of aquatic environments. Growing up to 60 cm tall, it features fine, cylindrical green flowering stems, with foliage reduced to a small tip on a tubular sheath that surrounds the flowering stem.

The terminal spikelets of Eleocharis acuta consist of small, brown, bract-like flowers grouped into compact, cylindrical clusters about 3 cm long, resembling a small tip at the end of the flowering stem. These flowers bloom primarily in Spring and Summer, adding a subtle elegance to its natural surroundings. The plant's understated form and texture make it a visually appealing yet functional component of wetland landscapes.

Thriving in waterlogged soils and tolerating full sun to partial shade, Common Spike-rush is highly valued for wetland restoration, riparian planting, and erosion control. Additionally, it provides critical habitat and food for wetland wildlife, including frogs, insects, and small birds, supporting biodiversity.

Widespread across a variety of wet habitats and easy to propagate, Eleocharis acuta is a practical and effective species for wetland revegetation projects. With its adaptability, ecological contributions, and understated beauty, it is a versatile choice for sustainable landscaping, biodiversity enhancement, and wetland rehabilitation efforts. Its resilience and functionality make it a key species for creating healthy, thriving aquatic ecosystems.
