Final answer:
American floral designs are a blending of Art Nouveau and American classical design.
Step-by-step explanation:
American floral designs are a blending of two diverse styles: Art Nouveau and American classical design.
Art Nouveau was a style that embraced the incorporation of designs into various decorative forms, including furnishings and architecture. It often featured female forms, plants, and flowers as common subjects. American classical design, on the other hand, was influenced by European gardens and landscape architecture, with a focus on ornamental arrangements of flower beds and fountains.
By blending these two styles, American floral designs combine the artistic and decorative elements of Art Nouveau with the botanical knowledge and ornamental arrangements of American classical design.
