What Does the Hemlock Know?

What does the lovely hemlock say
Amid mid-summer storms
Prevalent and principled
Exists as if the norm
To be so terribly poisonous
And feared in stories old.

Yet with every summer
In each pasture, roadside fence
The hemlock thrives among
Those side by side, cattle whom
Heads are down to graze
Just browsing 'round they roam.

Now mid-summer suddenly sees
Hemlock dry and brown
Amid a rainy summer
It prepares for early fall.

"What does the hemlock know", I say
"Why is it leaving now?"
A wise and fearsome plant it is
And yet it's gone away.
