In general, pesticides are applied to ornamental plants to protect against crop damage by insects, diseases, and additional plant pests, but it is equally important that pesticide applications themselves do not adversely affect commercialization
Non-native species are thought to comprise as much as 80% of the plant inventory held by nurseries in the United States ( Hulme et al. 2018 ). Although most introduced ornamental plants do not escape cultivation, some plants spread into natural

Abstract
As horticulturists and landscape professionals, we need to examine the traditional idea of “ornamental horticulture” in the context of environmental constraints, resource conservation, and social accountability in our highly urban society. The current over-emphasis on the ornamental use of plants in our landscapes reflects human tendencies toward conformity, eclecticism, and decorativeness in landscape design. An analysis of these tendencies along with the changing needs of our society suggests the new, broader term “appropriate horticulture,” emphasizing self-sufficiency in food and fuel production, urban needs, and an ecological orientation. This holistic concept of horticulture will allow horticulturists to become a more powerful force in our society.
