Christmas is celebrated during the winter months. Holly, with it's glossy leaves and red berries remains green throughout the season.
The Druids believed holly would remain beautiful when the sacred oak had lost its leaves. Druids wore sprigs of holly in their hair. Holly was also sacred to Saturn, the god honored at Roman Saturnalia celebrations. Romans gave one another holly wreaths and decorated images of Saturn with it.
Boughs of holly, are believed to have magical powers since they remained green through the harsh winter. The boughs would be placed over the doors of homes to drive evil away. The common practice of hanging a holly wreath on the front door continues today.
Religious beliefs state that holly sprang from the footsteps of Christ as he walked the earth. The pointed leaves were said to represent the crown of thorns Christ wore while on the cross and the red berries symbolized the blood he shed.
