Why does the author refer to a tree as unchanging?

April
by Sara Teasdale

The roofs are shining from the rain,
The sparrows twitter as they fly,
And with a windy April grace
The little clouds go by

Yet the back–yards are bare and brown
With only one unchanging tree—
I could not be so sure of spring
Save that it sings in me.

A. It is too sturdy to be moved by the wind.
B. It has not yet been pruned.
C. It does not have any leaves on it.

Firstly, you cannot always take a poem to seriously. She could have used that term just because it worked with her poem. She could though, mean that the tree is dead. A tree never stops growing, which means bit by bit, it is always changing. If it is dead it will remain the same until it breaks or someone breaks it. Seeing as it is April in the poem though, she could mean it doesn't have leaves on it yet and so it looks dead and therefore is unchanging. It is hard to tell what she really meant though, being as she has not put any further description of the tree. I hope I helped!
