St David is the patron saint of Wales. March 1 is his feast day.
Saint David (Welsh: Dewi Sant) was born towards the end of the 5th century. He was a scion of the royal house of Ceredigion, and founded a Celtic monastic community at Glyn Rhosyn (The Vale of Roses) on the western headland of Pembrokeshire (Welsh: Sir Benfro) at the spot where St David’s Cathedral stands today.
Many Welsh people wear one or both of the National symbols of Wales to celebrate St. David: the daffodil (a generic Welsh symbol) or the leek (Saint David’s personal symbol) on this day. The leek arises from an occasion when a troop of Welsh were able to distinguish each other from a troop of English enemy dressed in similar fashion by wearing leeks.
