The answer to 'what is hedge' is a row of closely planted shrubs or small trees that form a boundary or barrier. Hedges are commonly used in landscaping to mark property lines, provide privacy, or create visual interest in a garden. They can be shaped and trimmed into various forms, such as straight, curved, or even geometric patterns.
Hedges are often made up of evergreen plants like privet, boxwood, or yew, which retain their foliage year-round. Deciduous plants like hawthorn or beech can also be used to create a seasonal hedge that changes with the weather. The choice of plants depends on the desired look, climate, and maintenance requirements.
