Flower Fairies of the Trees

Look up!
Look up, at any tree!
There is so much for eyes to see:
Twigs, catkins, blossoms, and the blue
Of sky, most lovely, peeping through
Between the leaves, some large, some small;
Some green, some gold before their fall.
Fruits you can pick, fruits out of reach;

And little birds with twittering speech.
And, if you're quick enough, maybe
A laughing fairy in the tree!
