Mt. Auburn is an arboretum, as much of a garden as a cemetery. The saucer magnolia (picture above) was in bloom, along with lilac, azalea, honeysuckle, red horse chestnut, dogwood, and more.
The poet Robert Creeley is buried at Mt. Auburn. On one side of the stone is his name; on the other, this verse:
