The edible ﬂowers are sold as pot plants or fresh cut produce and are attracting interest recently thanks not only to their organoleptic characteristics but also to their content in bioactive molecules. However, there is little information about the variations that these characteristics undergo during postharvest. In this study, the productivity and longevity of Begonia x semperﬂorens-cultorum Hort. and Viola cornuta L. pot plants were evaluated in an interior environment simulating the house conditions. Besides, the eﬀect of cold storage (4°C) was evaluated on the aesthetic quality and the bioactive compounds content (total polyphenols, total anthocyanins, antioxidant activity through FRAP assay) of B. semperﬂorens and V. cornuta fresh cut ﬂowers, using two different packaging, modelling a plastic box or a ﬂowpack. The results suggest that V. cornuta could be a better choice for retailers because of its longer shelf life and better maintenance of its content in bioactive compounds, especially in the ﬂowpack packaging. Conversely, B. semperﬂorens could be more suitable as pot plant, showing more adaptability and ﬂower production in a domestic environment.
