Here, self-preservation is metaphor:
Two dry riverbeds that run the water
From the neighborhood to the reservoir
Hold the water when it rains, in order
That a semi-septic self-made swamp pond
On two grandfathered acres, that won’t perk,
Might be the birthplace of this flower on
This shallow marsh. Each spring I watch her birth.
The “Blue Flag”, out of the Iris family,
Has a throat of spectacled gold, and grows tall
On a solid single stem; fun, friendly
But at her roots she’s poisonous to all.
Self-preservation, as final duty,
Creates its own narcissistic beauty.
