Answer Details

Plants grown mainly for their decorative or aesthetic value are called ornamentals. This is a standard agricultural and horticultural classification. Ornamental plants are cultivated for their attractive flowers, foliage, shape, fragrance, or overall visual appeal rather than for food, fibre, or timber. Examples include roses, hibiscus, bougainvillea, crotons, and palms used in landscaping.

Hedges are a specific use of plants (forming a boundary or barrier), not a classification based on purpose of cultivation. Many hedging plants are ornamental, but "hedge" describes the planting arrangement, not the category. "Beautifiers" is not a recognised agricultural or horticultural term. "Flowers" refers to the reproductive structures of plants; while many ornamentals are valued for their flowers, the term "flowers" is too narrow because ornamental plants also include foliage plants, ornamental grasses, and ornamental trees that are valued for features other than their blooms.
