The Infiorata di Spello is one of Umbria's most celebrated Corpus Christi traditions, held each year on the Sunday of that feast. Residents spend the night before laying elaborate pictorial carpets made entirely from flower petals directly onto the paving stones of the town's streets. The designs frequently include religious imagery alongside geometric and decorative motifs, each neighborhood competing to outdo the last in intricacy and scale. The tradition has deep roots in Italian Corpus Christi celebrations but Spello's version has earned particular renown across the country.

The carpets are at their most vivid in the morning hours before the procession begins, when the petals are still fresh and the color is at its most intense.
