''. A fanciful etymology explains the name 'serviceberry' by noting that the flowers bloom about the time roads in the Appalachian mountains became passable, allowing circuit-riding preachers to resume church services. A similar etymology says that blooming serviceberry indicated the ground had thawed enough to dig graves, so burial services could be held for those who died in the winter when the only way to deal with the bodies was to allow them to freeze and wait for spring. Both of these fanciful etymologies are unlikely to be correct since the term is attested for both English and New World species as early as the 16th century, well before settlement of English North America, and serviceberry is far from unique in blossoming early in the year.
