Headnote: "For the poetry contest at the Teiji Palace"
Playing on the name Kagamiyama, "Mirror Mountain," the poet calls on the mountain to hold the flowers' color like a mirror, so that their image might still be seen after spring has passed. Making use of the mirror implied in the place name, the poem expresses regret for departing spring. According to the headnote, it was submitted to the poetry contest at the Teiji Palace.
Sakanoue no Korenori was a descendant of Sakanoue no Tamuramaro and a poet of the early Heian period. He is counted among the Thirty-Six Immortal Poets.

First line, "hana no iro o," names the flowers' color as what the poet wishes to keep.
Second line, "utsushitodome yo," is a pivot word combining "reflecting" in a mirror and "transferring" the flowers' color, calling on the mountain in the imperative; the poem pauses after the second line.
Third line, "kagamiyama," is a famous place in Ōmi whose name evokes a mirror.
Fourth line, "haru yori nochi no," means "after spring is gone."
Final line, "kage ya miyuru to," with "kage" meaning image or form, means "in case their form might still be seen." It takes up the wish for a keepsake of spring in the preceding poem.
