Ornamental plants are plants that are grown for decorative purposes with a range of shapes
Ornamental plants are plants that are grown for decorative purposes with a range of shapes, sizes, and colors that are suitable to a broad array of climates, landscapes, and desired gardening characteristics (their ?owers, leaves, scent, overall foliage texture, fruits, stems and bark, and aesthetic form). Ornamental plants broadly comprise various types of plants, from herbaceous to woody, lower to higher level, and aquatic to terrestrial plants(Liu et al. 2007; Dobres 2011). Distinguished from other types of reported remediation plants, some ornamental plants can beautify the environment while also remedying contaminated soils(Fig.1), particularly in urban areas (Han et al. 2007; Y. Sun et al. 2011; Wangetal.2012;Cuietal.2013;Selamatetal.2014;Ramanaetal. 2015). Optimistically, both economic and ecological bene?ts can be expected with the application of ornamental plants for the phytoremediation of contaminated soils. A contaminated area can be developed for ecotourism by growing ornamental plants to preserve the aesthetic beauty of the land. After arti?cial culturing, ornamental plants could also be sold as houseplants, which will result in economic bene?ts and save a large amount of the ?nal disposal expenses (Liu et al. 2006).
