Central to Klee's artistic worldview was his connection to nature. He was particularly fascinated by the plant world. He observed it with an inquisitive eye, analyzing flower forms, stem segmentation, and leaf veins. Goethe's natural philosophy and his theory of the archetypal plant profoundly influenced him, and in his teaching at the Bauhaus, he incorporated botany alongside mathematics, physics, and perceptual psychology. Essentially, his aim was to extract fundamental principles from the forms and growth processes of nature that could be applied to art. Despite his quasi-scientific interest in nature, the majority of his depictions of nature went far beyond this theoretical approach, and nowhere in his work did his imagination flourish as unrestrainedly and profoundly as in his "botanical theater." Human and plant life merge, creating a fantastical flora imbued with delicate emotions as well as ardent passions. The entire spectrum of human emotions is reflected in seeds, blossoms, and fruits, as well as in the numerous depictions of mysterious gardens. Klee staged a veritable theatrical spectacle in his painting "The Feast of Asters." He grouped the vibrant plants, which provide color and floral splendor in gardens well into late autumn, in a choreographic order and framed them with billowing curtains. Roots, leaves, and blossoms are strictly stylized and seem to turn luminously toward the viewer; the nocturnal atmosphere enhances the brilliance of their appearance. At the same time, the violet base color with its streaked white highlights seems to herald decay and present "The Feast of Asters" as one of nature's last displays in the cycle of the seasons.
