I found 2 conkers in my desk drawer.
I could return them to the forest floor
Where they would rot and be one
With fruits and flowers long since gone.
Autumn is in the air,
Yet I do not care
To return them to the ground.
A thought, perhaps profound,
We are all bound
To join Mother Nature’s great store
When we, as leaves fall
And become as one
With generations long gone.
Conkers may be put away
In a drawer.
But Autumn’s fall
Says all things must decay.
K Morris - Poet 
The conkers might not rot away if returned to the forest, but grow into beautiful trees!
You make a good point, Vivienne. Checking online I learned that conkers may indeed grow if stored in certain conditions, for example in a damp, cool place. However, they are unlikely to sprout if stored in drawers at room temperature. I’ll have a think about my poem in the light of your comments, for which thanks again
