Cyperus papyrus aka Papyrus

Cyperus papyrus, also known as papyrus, papyrus sedge, paper reed, Indian matting plant, or Nile grass, is a tender herbaceous perennial belonging to the sedge family Cyperaceae. Native to Africa, this aquatic flowering plant forms tall stands of reed-like swamp vegetation in shallow water. It has a long history of use by humans, particularly the Ancient Egyptians, who used it as the source of papyrus paper. The plant has multiple uses, as its parts can be eaten, and its buoyant stems can be made into boats. Nowadays, it is commonly cultivated as an ornamental plant. In the wild, it thrives in full sun, flooded swamps, and on lake margins across Africa, Madagascar, and Mediterranean countries. It has also been introduced to tropical regions worldwide. This densely tufted perennial sedge can reach a height of 1.2m and features dark green stems that bear spherical, terminal heads of grass-like leaves. During summer and autumn, small spikelets of tiny brown flowers appear on the stems. The plant can grow up to 4 to 5m high and forms a clump of triangular green stems with feather-like, bright green thread-like stems on top. Greenish-brown flower clusters eventually give way to brown, nut-like fruits.
