Put this on the crazy end of the spectrum - there is a Banana Slug String Band with a whole album about gardening. "Each song is a great leap into garden-related lessons, from plant parts ("Roots, Stems, Leaves") to the water cycle ("Water Cycle Boogie").

You have to hear "Give Plants a Chance", the first cut off the album. It's so goofy it made me laugh. Good grief, I'll probably catch myself humming it as I work out back.
