[Display omitted] •Edible mini-roses were farmed in different organic systems and evaluated.•Mini-roses farmed in biocompost form discarded fruits had higher anthocyanins levels.•Mini-roses farmed in biocompost had more volatiles related to fruity aroma.•The farming system influenced the abundance of microbial groups in mini-roses.•Mini-rose farmed in biocompost received higher fruity aroma and red color scores. Mini-roses (Rosa chinensis Jacq.) is largely used in salty dishes and desserts. This study evaluated instrumental color, sugars, organic acids, phenolics, volatiles, and the indigenous microbiota (fungi and bacteria) in edible mini-roses farmed in discarded fruits biocompost and animal manure systems. A descriptive sensory analysis of flowers was also performed. Mini-roses farmed in biocompost had higher luminosity and intensity of instrumental red color, a higher concentration of phenolic compounds, including anthocyanins related to red color, and fructose than mini-roses farmed in animal manure (p
