Who is the patron saint of gardeners? It's not St. Francis.

St. Fiacre (also known as Fiachra; Fiachrach; Fiacrius; Fiaker and Fevre) was a hermit at Kilfiachra, Ireland. He left to go to France, and then lived as a solitary at Breuil, Brie, on land given him by St. Faro, bishop of Meaux. Fiacre built a hospice for travelers, attracted many disciples, was known for his charity and aid to the poor, and was consulted by many for his spiritual wisdom. His miracles of healing became legendary. He is the patron saint of gardeners and the cabdrivers of Paris, whose vehicles are called fiacres, since the first coach for hire in Paris was located near the Hotel Saint-Fiacre. He is mentioned in Roman Martyrology for this day.
