Did you know?

Hazel trees are common in England, and their sweet nuts become ripe in late summer. The feast day of a French saint named Philibert was celebrated during the time that people picked these nuts. In 1066 the Normans conquered England and in their form of French they called the nut of the hazel tree philber, after the saint. Eventually, English borrowed the word as filbert.
