"Though I'm poor to human eyes
Really I am rich and wise.
Every tiny flower I shed
Leaves a heart-shaped purse instead.

In each purse is wealth indeed-
Every coin a living seed.
Sow the seed upon the earth-
Living plants shall spring to birth."

Verse 1 & 2, The Song of the Shepherd's Purse Fairy by Cicely Mary Barker
