There are several different reasons why people engage in this tradition. In Ireland, this practice was believed to ward off evil, and bring good luck to those who took part in the practice. It is also typically associated with The Virgin Mary; May being "Mary's Month" in the Catholic Faith. Lara Maynard writes:
"Newfoundlanders who erect may bushes nowadays usually cite the commemoration of "Mary's month" as the reason for doing so. Indeed, their may bushes are often predominantly or solely decorated in blue ribbons, blue being the colour often associated with Mary in iconography. Some people add red ribbons to their bushes in June in commemoration of the Sacred Heart of Jesus and do not take them down until the end of that month."
I am looking to collect narratives from residents of Logy Bay-Middle Cove-Outer Cove who still take part in the may bush tradition. Please contact Katie at lbmcocmuseum(at)gmail.com or (709) 726-5272 if you have any information.
