This article will chart the usage of a rare term, uiridarium, in the documents of early medieval Italy in order to explore the history of decorative or pleasure gardens between c.600–c.1000. Property documents and placita, alongside a small body of archaeobotanical evidence, suggest a significant change in the planting of cultivated spaces in Italian cities during the early Middle Ages. A few charters refer to enclosed gardens called uiridaria attached to houses of the highest‐status people in Italy: dukes, kings, emperors, and bishops. We have a glimpse of how they were used and this article makes the case that decorative gardens played a role in the urban performance of the highest echelons of power.
