“…Hundreds of species of many botanical families used intensively in commercial floriculture and garden plants and traded commercially as ornamentals (Heywood, 2001). The success of the new floricultural products in the market can be increased if the ornamental desirable traits were determined by specific criteria (Stumpf et al, 2007), such as the morphological characteristics of the plant, as regard to its novelty or aesthetic value (Tognon and Cuquel, 2016). A better understanding of consumers' preferences for native plants, their attitudes toward bringing a more naturalistic landscape design and the assessment of their purchase behaviour may allow a better characterization of the market for producers of native plants (Nils Peterson et al, 2012;Alam et al, 2017).…”
