What does it take to paint a wildflower that blooms for a single day in a deep forest? For Mary Vaux Walcott, it involved spending up to seventeen hours a day out of doors with her paintbox to capture the shape, movement, and colors of delicate petals and leaves. Originally published in 1925 to enormous acclaim in five, oversized volumes, Walcott’s sketches introduced the diversity and beauty of North American plants to the general public. A selection of some of the most stunning illustrations are now available in a single volume, these illustrations have lost none of their beauty or realism. Walcott’s technique involved precise attention to detail, color, light, and perspective. Her art can also be appreciated as the work of a woman scientist battling the prejudices against her sex of the day. She was an intrepid explorer, skilled geologist, and generous benefactor to the Smithsonian Institution at a time when women’s accomplishments were often overlooked or misattributed. As inspirational and informative as they are a pleasure for the eyes, this bouquet of nature’s fleeting gifts is a lasting treasure of botanical and scientific artistry.
