another decent recent found find: richard wilbur's "pasture poem" a couple new yorkers ago

This upstart thistle
Is young and touchy; it is
All barb and bristle,

Threatening to wield
Its green, jagged armament
Against the whole field.

Butterflies will dare
Nonetheless to lay their eggs
In that angle where

The leaf meets the stem,
So that ants or browsing cows
Cannot trouble them.

Summer will grow old
As will the thistle, letting
A clenched bloom unfold

To which the small hum
Of bee wings and the flash of
Goldfinch wings will come,

Till its purple crown
Blanches, and the breezes strew
The whole field with down.
