Rose Sunday. In history this was the time when folk returned to their "mother church", the main church or cathedral in their area, to celebrate Laetare Sunday or mid-Lent or Simnel Sunday. The liturgical color is pink or rose. For many Church of England churches this is the only day in Lent when marriages can be preformed.
Allan Titchmarsh, English landscape gardener and television journalist and writer, has written a wonderful column in the Telegraph on his memories of Mothering Sunday (not to be confused with Mother's Day).
