Just found this one in MsJ's Types of Poetry section and had to try it!
Zejel - a humorous poem, usually 8 syllables per line, but this can vary. First verse is 2 or 3 rhyming lines and following verses are 3 rhyming lines and then another line that rhymes with the last line of the first verse. For more in-depth information see the "Types of Poetry" section.

Garden Pride
I plant my ivies and flowers,
leaving growth to nature's powers.
I take great pride in my plant's bed.
English Ivy, Wandering Jew,
my Moses plant is pretty too!
I love to find ones that are new.
All of them get very well fed.
I planted one and was amazed,
at how it spread and why it raised,
shouts of laughter and was not praised.
Near the root it was turning red.
Healthy green leaves in sets of three,
the bed was completely weed-free.
Nothing was wrong that I could see.
But 'twas poison ivy instead!
