Gräser, or grasses, are a large family of plants known scientifically as Poaceae. They are characterized by their narrow leaves and hollow stems, which often grow in clusters. Grasses are found in a variety of habitats, including meadows, forests, and wetlands, and they play a crucial role in many ecosystems by providing food and shelter for wildlife. Grasses are also important for agriculture, as they include staple crops like wheat, rice, and corn. These plants are typically adapted to grow in diverse climates and soil types, making them essential for both natural landscapes and human cultivation. Their ability to thrive in various conditions contributes to their widespread presence around the world.
