If I have a favorite tree, it is the cottonwood.
No, I don't have to put up with its cottonwood in the springtime, or the allergies, but to me, it bespeaks the color and abundance of water in New Mexico.
My favorite, tree, which I've tried to paint many times, is at the corner of Alameda and Paseo de Peralta, in Santa Fe.
So to, pushing and hoping for the muse, here is my Cottonwood series... 5 x 7 watercolors.
Spring, early fall at its most brilliant, before the snow falls, and in January plus a painting of my favorite tree.
