wild iris (ayame) seen along Whitefish Bay

Wild purple iris
on the path to the water
one midsummer’s day

Frank J. Tassone is the host of Haikai Challenge.  Frank says:
Like the mayfly, the bloom of [the wild iris (ayame)] lasts but a single day. What better exemplar of transience can we ask for?  This week, write the haikai poem of your choice (haiku, senryu, haibun, tanka, haiga, renga, etc.) that alludes to the wild iris (ayame).
