a single night and then go home,
would wisteria flowers
show to you their colors
with a heart that's opened wide?
Meaning
If you sleep here but a single night and then go home, would the wisteria ever show you its colors with a heart fully opened?
Commentary
Book Three Spring Poems III 129

Headnote continued from the preceding poem: "While they were playing the koto and flute and talking, the night grew late, and so the guest stayed over."
As host, the poet asks his guest to stay longer, saying that if he leaves after one night, the wisteria will not show him its colors with an open heart. Taking up the "sleep" and "color" of the preceding poem, he entrusts to the wisteria his wish that his guest linger.
The three poems from 128 to 130 form a sequence exchanged the morning after Sadakata stayed the night, when the same banquet as in the three preceding poems had continued late into the night.
The poet, called "Lord Kanesuke," is Fujiwara no Kanesuke. A son of Fujiwara no Toshimoto, he rose to Middle Counselor. He was called the Tsutsumi Middle Counselor because his residence stood on the embankment of the Kamo River, and he was a patron of Ki no Tsurayuki, Ōshikōchi no Mitsune and others. He was the great-grandfather of Murasaki Shikibu and is counted among the Thirty-Six Immortal Poets.

The first line, "Hitoyo nomi," means "only one night," taking up the night's sleep in the preceding poem, 128.
In the second line, "shi" is emphatic and "ba" conditional: "if you sleep and then go home."
The third line, "fuji no hana," names the wisteria of the host's house, overlaid with the host's own heart.
The fourth line, "kokoro toketaru," means "opened in heart," laying the unfolding of the flowers over a heart that warms. "Uratokete" in 100 of this book also sings of a heart opening.
In the last line, "ya wa" is rhetorical: "would it show you? It would not."
