An ornamental plant is decorative: it is grown for how it looks, and not for other values. The term is often shortened to ornamental, used as a noun
Ornamental plants are plants that are grown for decoration. They are on display in gardens, landscapes and inside houses. They can be used indoors as cut flowers or potted plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a major branch of horticulture.
