What is a failed haiku?

Pat Daharsh lives in Florida and writes haiku. Recently she submitted another form of short poetry,  Senryū  to  https://failedhaiku.com.  

The editor liked her poems and published five of them. Pat says, "It’s an ‘acquired taste’ for some. I don’t write a lot of it, but now and then I realize that’s what I’ve written instead of haiku – and occasionally I write one or two on purpose." 

Senryū is a Japanese form of short poetry similar to haiku in construction. Senryū tend to be about human foibles while haiku tend to be about nature, and senryū are often cynical or darkly humorous while haiku are more serious. 

This Editor says further – “Many years ago, at a haiku meeting, someone asked me what my definition of a senryu was, and I said: “It is just a failed haiku is all.” It was a flip answer, not particularly literary, but I have grown to like it for both its brevity and its lack of preciseness, both of which fit the spirit of senryu perfectly.”

bruised sky -
the lab tech searches
for a vein

snowmelt…
the road less traveled
reappears

laundry day
grey sheets of rain
unfolding

workday morning
the burnt toast odor
hitches a ride

always polite
a child waves goodbye
to the waves

Congratulations, Pat. I like these short poems. Readers, try writing some yourself. Send them to me and I will share them with the world.
