Joshua Tree

I tried once to write about a Joshua Tree,
How it scrubs the desert air with many arms,
But I who live among the Oak and Maple,
Beside the Poplar, alongside Willow sweeps,
With Fir and under reaching Pine,
Who watch the Tamarack coat the earth
With tiny golden combs, who wait
For Redbud signs of spring,
Whose Serviceberry, Apple, Pear, and Plum
Make drunk the bees, sate the birds,
Then drowse in lazy autumn,
I could not find the term for that
Flintstone desert plant.
I could perhaps try crayon,
Pale yellow, black, some green,
Not this pack of forty-eight,
Not these fat words I wrap my hands around,
Not Sweetgum. Cottonwood. Persimmon.
Not Deciduous. Majestic. Not this ever ever green.
