If you want a Russian Thistle,
All you have to do is whistle –
In they tumble on the breeze.
An 1800s stowaway,
A foreign sprout who’s here to stay
Blowing ever West with ease.
Not a thistle, but as hairy,
From the steppes to claim the prairie,
Infiltrating cowboy lore.
Full of thorns and full of seeds,
These drifting immigrants are weeds
Just made to be a metaphor.
