Now called teagardens. Nothing to do with cherries; it is cheery fairs —i.e. gay or recreation fairs. A “cheering” is a merrymaking. Halliwell tells us that “Cherry (or rather chery) fairs are still held in Worcestershire.” Gower says of this world, “Alle is but a cherye-fayre,” a phrase frequently met with.
“This life, my son, is but a chery-fayre.” —MS. Bodl. 221 (quoted by Halliwell).
