神垣にかかるとならば朝顔も
ゆふかくるまで匂はざらめや

Roma-ji: Kamigaki ni kakaru to naraba asagao mo yū kakuru made niowazarame ya
English Translation: If it twines upon
the sacred fence of the gods,
then the morning glory
until evening's cotton strips
how could it not bloom on bright?
Meaning: If it twines on the sacred fence of the shrine, how could even the morning glory fail to bloom until evening, when the sacred cotton strips are hung?
Commentary: Book Three Autumn Poems 114

Headnote: "... composed on morning glories blooming and twining there"
The author is listed here as an unnumbered poet, but the Shikashu attributes the poem to Princess Baishi, the Rokujō Kamo Priestess. In the source consulted, the beginning of the headnote is illegible. The poem depicts morning glories blooming on a shrine fence.
Morning glories fade by midday, yet having twined on the gods' fence, they will bloom until evening under divine protection. Using the pun on yū, sacred cotton and evening, the poem blesses the morning glories of the sacred precinct.

The first line, "kamigaki ni," means "on the shrine fence," showing that this is sacred ground.
The second line, "kakaru to naraba," is a supposition: "if it twines there."
The third line, "asagao mo," means "even the morning glory," mo implying even a flower that should wither.
In the fourth line, "yū kakuru made," yū is a pivot word joining the sacred cotton offered to the gods and evening, meaning both "until cotton is hung" and "until evening."
The last line, "niowazarame ya," is rhetorical: "how could it not bloom?" meaning it surely will.
