Thistle seed?

Just because we name something thistle...it ain't necessarily so.

The thistles
Finally flower
We have been waiting
Wondering
Which insect
Which bird
Needs
The thistle
For sustenance.
No
It is not the goldfinch.
Thistle seed
Is a misnomer.
The seed
Finches pine for
Comes from Asia.
Or Africa
It is hardly
From thistle
At all.
There
The natural history
Lesson
For today.
Which insect
Which bird
Will visit.
We will watch.
