👉 Willowweed is a type of grass that grows along waterways, often in the form of small, wiry stems or blades that emerge from the ground and grow towards the surface, forming a lush carpet-like appearance when they reach their full height. This species can be found in wetlands, rivers, lakes, and other bodies of water where it serves as an important habitat for many plant species and is often used in landscaping for its aesthetic qualities.
