History and folklore

Blackthorn blooms white on bare black branches in early spring, often during a cold snap that country people called a blackthorn winter. Its wicked thorns made it a hedge plant for keeping livestock in and intruders out. In Irish tradition the shillelagh walking stick was often made of blackthorn, and in folklore the tree was linked to fate, curses and the dark half of the year. Witches use blackthorn for strong protection, boundaries and banishing.
