in florology, means “Good Hope,” because it shows the winter is over and spring is at hand. The Athenian girls used to crown themselves with hawthorn flowers at weddings, and the marriage-torch was made of hawthorn. The Romans considered it a charm against sorcery, and placed leaves of it on the cradles of new-born infants.
The hawthorn was chosen by Henry VII. for his device, because the crown of Richard III. was discovered in a hawthorn bush at Bosworth.
