A Tan Renga is a poem written by two poets. This challenge asked participants to write a second stanza for the given haiku.  The first stanza is a haiku written by  © Chèvrefeuille.  I added on the second stanza, also in haiku form.

in the moonlight
Wisteria flowers look fragile –
a gust of wind

invites them to
dance with their shadows,
then smooth their skirts and rest again.
