Answer

It is wild in the past and nature is fully in control ‘nature’s easy will’ although this is not violent, it is a controlled, almost lazy manner.

The landscape includes ‘grasses that never knew a scythe’ which appears like waves in the summer breeze.

The alliteration on ‘wild weed blossoms waken’ gives a sense of power with the hard ‘w’ sound energising the power of the wind and the wildness of nature.
