Coyer's last series of work was based upon still lifes of flowers. Coyer had explored other genres; this one is a dangerous subject for a contemporary artist to handle, for it immediately opens him to charges of inconsequentiality and pandering to popular tastes. This is not something new; it has been noted how the academic tradition ranked still life painting as the lowest form of painting, as the artist was "merely" copying what he saw before him. Flowers have also been the traditional subject of the Sunday painter.

Coyer's floral works, however, are art about art. The subject of the paintings are not flowers painted from life. Instead, the artist has drawn on models from seventeenth century Dutch painters to the American Impressionist Frank Benson. Coyer takes vases and other vessels from those paintings; the flowers themselves were usually drawn from photographs of flowers The paintings are a paeon not to nature but to the artist's recreation of nature in art.

The works are beautiful, but certainly not in a conventional fashion. Coyer scrapes away, overpaints, and otherwise alters his first strokes. Many of the works have the floral container set atop a round table, whose plane is set on a different perspective than the container's. In other paintings, the flowers are juxtaposed with Frank Lloyd Wright's architecture, particularly "Falling Water." That house was Wright's most famous attempt to have a building situated harmoniously within its environment. For Coyer, however, the building has always seemed an ambitious failure; the technology of 1936 was insufficient to handle the stresses put on the cantilevers by gravity and the problems of humidity from the stream over which the house rests. The building is not one with nature, but rather one against nature. Coyer uses it in the floral works as an emblem of the artist's impulse to bend nature to his esthetic impulse. The irony here, of which Coyer is fully aware, is that the "nature" to which Wright's architecture is here contrasted is not taken directly from life but is rather Coyer's own interpretation of an earlier interpretation of nature.
