17-19 June. The annual flower festival, or “infiorata”, takes place at Genzano south of Rome from 17-19 June. The ancient festival, now in its 239th edition, is held each year on the occasion of the Feast of Corpus Domini.
The flower festival features up to half a million petals, blooms and seeds which are used to carpet the town’s main street with spectacular floral illustrations.
