In her 1974 book, O’Keeffe explained: “The meaning of a word— to me— is not as exact as the meaning of a color. Color and shapes make a more definite statement than words.” Her exacting, expressive color intrigued. The Precisionist painter Charles Demuth described how, in O’Keeffe’s work, “each color almost regains the fun it must have felt within itself on forming the first rainbow” (As quoted in C. Eldridge, Georgia O’Keeffe, New York, 1991, p. 33). As well, congruities between forms knit together her oeuvre. Subjects like hills and petals undulate alike, while antlers, trees, and tributaries correspond in their branching morphology.

The sinewy contours and gradated hues characteristic of O’Keeffe find an incredible range across decades of her tree paintings. In New Mexico, O’Keeffe returned to the cottonwood motif many times, and the seasonality of this desert tree inspired many forms. The vernal thrill of new growth was channeled into spiraling compositions like Spring Tree No.1 (1945). Then, cottonwood trees turned a vivid autumnal yellow provided a breathtaking compliment to the blue backdrop of Mount Pedernal. The ossified curves of Dead Cottonweed Tree (1943) contain dramatic pools of light and dark, providing a foil to the warm, breathing quality of this painting, Cottonwood Tree (Near Abiquiu). The aural quality of this feathered cottonwood compels a feeling guided by O’Keeffe’s use of form of color.
