classic plant breeding has increased the beauty and utility of ornamental plants, but through the application of biotechnology  completely new traits could be developed in plants. Creation of blue color petal in carnation and rose are examples demonstrating   the optional of biotechnology in creating novel traits out of the scope of the conventional hybridization.  Application of genetic engineering in ornamental plants is not limited to changes in color.  Resistance to pests and diseases, enhancement of flowering, extended cut flowers life and modification of flower structure are examples of other important traits that could be modified using modern biotechnology. It is predicted that genetic engineering will revolutionize ornamental plants industry in the future. With the introduction of any new technologies, concerns are raised about their safe use and deployment. Concerns have also been raised about the possible negative impacts of commercialization of genetically modified (GM) ornamental plants on the ecosystem. The concerns have several different origins and providing responses to these concerns and not addressing them is the main objective of this paper. This article considers GM ornamental plants in the context of current ecological risk assessment principles, research results achieved, and current regulatory frameworks.This article can be very useful for biotechnologists, biosafety specialists, and authorities concerned.
