Green Mound

Okay, imagine you have a big pile of sand or dirt. You can shape it however you want, maybe into a mound that looks like a hill. Now, imagine that instead of sand or dirt, you have a special kind of grass that stays green all year round. When you shape this special grass into a mound, you have what's called a green mound! It's like a green hill made out of grass. People might make green mounds in their gardens or parks to create a nice, natural-looking feature that adds some interest to the space.
