Ice haiku

  

Tuft of grass

 green as summer

Frozen in ice.

Small seed 

stuck on ice

 far from home below.

Laden limbs

 cannot reach the sky.

Come spring, they'll try.

Gentle lines

not nature, but by fairy maid

Gone, come spring.

  

Bubbles,

strings of DNA

frozen in ice.

I thought at first that haiku had to adhere to a formula of a certain number of syllables per line, 5,7,5. 
That pattern belongs to a specific style called "hokku".
Some Haiku can be 3,5,3 or 5,3, 5
English haiku is a total of 10-14 syllables, but can be up to 17. 
Some haiku poets feel that their poems should be expressed in one breath.
A haiku can be a single line or merely one word long.  Bottom line ?  Make up your own rules.  Enjoy !

Haiku of four lines  or longer have been written, some of them "vertical haiku" with only a word or two per line. These poems mimic the vertical printed form of Japanese haiku.
