Joyce Kilmer wrote a famous poem about trees but almost every other poet I know has done a tree poem at some time – – –

Edna St Vincent Millay

Thus in the winter stands the lonely tree
Nor knows what birds have vanished one by one,
Yet knows its boughs more silent than before:
I cannot say what loves have come and gone,
I only know that summer sang in me
A little while, that in me sings no more.

Christina Rossetti
I plucked pink blossoms from mine apple-tree
And wore them all that evening in my hair:
Then in due season when I went to see
I found no apples there.

D H Lawrence

Here there’s an almond tree—you have never seen
Such a one in the north—it flowers on the street, and I stand
Every day by the fence to look up for the flowers that expand
At rest in the blue, and wonder at what they mean.

Federico Garcia Lorca

Tree, tree dry and green…

William Shakespeare

Orpheus with his lute made trees
And the mountain tops that freeze
Bow themselves, when he did sing…

I could go on…. What is it about trees? Answers on a postcard….
