Chionochloa is a genus of grasses native to New Zealand and parts of the Southern Hemisphere. These grasses are commonly known as snow grasses and are characterized by their tall, slender stems and dense tufts. They thrive in alpine and subalpine environments, often found in mountainous regions. The genus includes several species, which play a crucial role in their ecosystems by providing habitat and food for various wildlife. Chionochloa grasses are also important for soil stabilization and are often used in restoration projects to combat erosion in their native habitats.
