“…In general, increased concentration of a contaminant usually negatively affects various growth parameters as observed for a series of plant species with phytoremediation ability (Capuana, 2020). In I. germanica increased Pb concentration was associated with significant decrease of plant height as well as number of leaves per plant besides other parameters (Song et al, 2020), proving that biomass is negatively affected by increased concentration of this pollutant.…”

Iris plants are widely cultivated flowering ornamentals, with a long history of traditional use in Eurasia, where this genus is reaching the highest diversity. This paper aims to provide an overview on recent advances related to the phytoremediation potential of plants from the genus Iris, in order to promote the use of these species in phytoremediation programs. According to the relevant literature, eight species from genus Iris present phytoremediation potential (I. dichotoma, I. germanica, I. halophila, I. lactea, I. latifolia, I. pseudacorus, I. sibirica, I. wilsonii). The studies addressed potential of plants to mitigate toxic metals/metalloids (As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Zn), excess of nutrients (P, N), pesticides, petroleum hydrocarbons, pharmaceuticals as well as dyes. Most studies focused on wastewater treatment and environments contaminated due to mining activities. Main hindrances in upscaling this green technology remain mitigation of toxicity stress in plants during remediation and the disposal of resulting contaminated biomass. In this sense, use of beneficial microorganisms to alleviate phytotoxicity effects and new valorization possibilities of contaminated Iris spp. biomass have been proposed recently. Designing an entire cycle that includes phytoremediation and sustainable value chains for contaminated biomass could prove feasible and should receive more attention.

“…Indeed, the contact with ornamental plants, through their cultivation or contemplation, contributes to people's physical and mental health (Reis et al 2020). In this context, in addition to add value to the landscape, phytoremediation programs using ornamental plants affect the interaction of people with areas under remediation (Capuana 2020).…”

Phytoremediation is an eco-friendly and economical technology in which plants are used for the removal of contaminants presents in the urban and rural environment. One of the challenges of the technique is the proper destination of the biomass of plants. In this context, the use of ornamental plants in areas under contamination treatment improves landscape, serving as a tourist option and source of income with high added value. In addition to their high stress tolerance, rapid growth, high biomass production, and good root development, ornamental species are not intended for animal and human food consumption, avoiding the introduction of contaminants into the food web in addition to improving the environments with aesthetic value. Furthermore, ornamental plants provide multiple ecosystem services, and promote human well-being, while contributing to the conservation of biodiversity. In this review, we summarized the main uses of ornamental plants in phytoremediation of contaminated soil, air, and water. We discuss the potential use of ornamental plants in constructed buffer strips aiming to mitigate the contamination of agricultural lands occurring in the vicinity of sources of contaminants. Moreover, we underlie the ecological and health benefits of the use of ornamental plants in urban and rural landscape projects. This study is expected to draw attention to a promising decontamination technology combined with the beautification of urban and rural areas as well as a possible alternative source of income and diversification in horticultural production.

“…The benefits of phytoremediation include the aesthetic value of a green site that provides better habitat for native wildlife compared to the site prior to remediation. Ornamental vegetation can be used for phytoremediation where parks or arboretums are established for public use and enjoyment (Capuana, 2020). Phytoremediation reduces soil erosion and the spread of contaminants because of wind and water.…”
