Restios are a group of grass-like plants primarily found in South Africa. They belong to the family Restionaceae and are characterized by their slender, reed-like stems and narrow leaves. These plants thrive in wetlands and sandy soils, often forming dense clumps. Restios play a vital role in their ecosystems by providing habitat for various wildlife and helping to stabilize soil. They are also popular in landscaping and gardening due to their unique appearance and ability to tolerate drought conditions. Some species are used in traditional crafts and as ornamental plants.
