Ornamental plants are plants that are grown for decorative puproses in gardens and landscape design projects, as house plants, for cut flowers and specimen display. The cultivation of these forms a major branch of horticulture. Most commonly ornamental garden plants are grown for the display of aesthetic features including: flowers, leaves, scent, overall folige texture, fruit, stem and bark, and aesthetic form. In some cases, unusual features may be considered to be of interest, such as the prominent and rather vicious thorns of Rosa sericea and cacti. In all cases, their purpose is for the enjoyment of gardeners, visitors, and/or the public. Similarly certain trees may be called ornamental trees. This term is used when they are used as part of a garden or landscape setting, for instance for their flowers, their texture, form and shape, and other aesthetic characteristics. In some countries trees in ''utilitarian'' landscape use such as screening and roadside plantings are called amenity trees.
