No more walks in the wood:
The trees have all been cut
Down, and where once they stood
Not even a wagon rut
Appears along the path
Low brush is taking over.
No more walks in the wood;
This is the aftermath
Of afternoons in the clover
Fields where we once made love
Then wandered home together
Where the trees arched above,
In the  language of flowers  (see link), white clover is traditionally associated with promises. Here it may symbolize the promises of young love.
