Definitions for "ornamental"
a plant cultivated for aesthetic purposes.
A plant that is grown strictly for its foliage or flower rather than for food or any other economic use (i.e. saucer magnolia.).
Any tree or plant that is planted for its beauty. This does not mean that it has no other uses. For example, Chlorophora excelsa is often planted as an avenue tree along roadsides (in Uganda); its stately appearance in no way diminishes its usefulness for timber. Ornamentals with other uses in agroforestry are the Cassias and Senna spp.
