Haiku are short poems which originated in Japan and which often refer to nature. Their short, rhythmic format has made them popular around the world. In English the usual structure is three lines of five, seven and five syllables. 

Matsuo Basho (1644-1994)) is the most famous haiku writer. Here are a few of Basho's haiku (translated into English). 

The bee emerging
from deep within the peony
departs reluctantly
Wet with morning dew
and splotched with mud, the melon
looks especially cool
Low tide morning
the willow skirts are tailed 
in stinking mud

Recently, Science magazine published Elemental haiku, (by Mary Soon Lee), a periodic table composed of 119 science haiku, one for each element. 

The haiku for boron mentioned plants: 

Just doing your job
holding plant cell walls together
No fireworks, no fuss

Inspired by this, Jose Dinneny wrote a haiku about sodium:

Scourge of plant and man
Questions persist how you're sensed
The roots may know, tell! 

Which gave us the idea of challenging plant scientists to write haiku about plant science! To motivate you, we've asked a few members of the Plantae Steering Committee to identify the best haiku submitted here by the end of September (midnight on Saturday Sept 30th Eastern Daylight Time). The winning author will receive a $50 gift card from Amazon. Judging will be based on both the incorporation of plant science as subject matter and the elegance of the poem, as determined by the judges.
