About rock bulrush
Schoenoplectiella juncoides is a sedge (a member of the Cyperaceae family), native to east Asia and Oceania. It is a serious weed of rice paddies. S. juncoides, also known as Kaluha or rock bulrush, belong to the Cyperaceae family. It is indigenous to Hawaiʻi but is also native to Madagascar and North America. Kaluha is not like the average flower species, as it does not grow bright, scented flowers. Instead, it grows tall leaves with spiky flowers annually. This species may improve this environment in ways such as preventing erosion and providing a habitat for some species. In other environments such as rice fields, it is considered invasive and could reduce crop yields.
