“Gardeners and taxi cab drivers have a patron saint in St. Fiacre. Said to be the illegitimate son of a Scottish king, he was raised in County Kilkenny at a Kilferagh monastery. He developed a local reputation for healing and herbal remedies.
Finding notoriety unsettling, Fiacre went on a quest for solitude to France eventually ending up in a deep woods cell. St. Faro, bishop of Meaux, offered him land for a farm. Instead, St. Fiacre built a small hut surrounded by a garden.
Fiacre honored the Blessed Virgin with an oratory. He built a hospice that became Saint-Flacre at Seine-et-Marne. Known for great charity, he attended to travelers and the poor alike. Not uncommon for monasteries then, he banned women from entering.
Fiacre’s feast day is celebrated on Sept. 1. He often is shown in a garden setting holding a shovel in one hand and bible in the other.” — http://www.catholicsaintmedals.com/St-Fiacre-medal.aspx
