Greenery refers to green plants, leaves, and vegetation, especially when they're used for decoration or when they create a lush, natural appearance. When a room is decorated with greenery for a party, it might have potted ferns, leafy branches, or vines draped across tables. When someone describes a park or garden as full of greenery, they mean it's rich with green, growing plants.

The word captures that fresh, living quality of plants. A city planner might add more greenery to downtown streets by planting trees and creating garden spaces. Interior designers use greenery to make rooms feel more alive and welcoming. During winter holidays, people often bring greenery like pine boughs or holly into their homes, adding color and life when outdoor plants have gone dormant.

Greenery can describe anything from a single houseplant brightening a windowsill to an entire forest canopy. It's the collective presence of green, growing things that makes a space feel natural and vibrant.
