About the maple seeds

The house on the corner, it has
An old maple tree smack in the middle
of its side yard.
When I walked by today
That tree looked dead, but wasn't,
On closer inspection.
Far from it, just the opposite.
For it's full, beyond full, of seeds,
Light brown, comma-shaped,
Whirling-like-heliocopters
Maple seeds. More seeds than leaves
On the branches, so much so
The tree looked brown.
And down below, a lawn
Already peppered with seeds
Already flown in the wind.
Thousands upon thousands
Thousands on thousands
A thousand thousand thousand,
of single-winged aircraft,
Crash-landed, seed-side-down,
A potential maple-tree forest, yet I know--
Not one will grow.
