Which arrangement style emphasizes compactness and order over wildness?

The Biedermeier design is characterized by its focus on compactness and orderly composition, making it a distinctive style in floral arrangements. This style originates from 19th-century Europe and is noted for its symmetrical patterns and the use of circular shapes, which create a neat and tidy appearance. The Biedermeier design often incorporates a series of concentric rings of flowers, which contribute to its structured look and emphasize the arrangement's form rather than a natural, wild aesthetic.

In contrast, a wildflower arrangement typically embraces a more relaxed and free-flowing style, reflecting the untamed beauty of nature. Structural design may incorporate elements of geometric shapes and frameworks, but it does not inherently emphasize the same compactness and orderly layering that define the Biedermeier style. A garden arrangement often mirrors the natural, sprawling characteristics found in outdoor settings, allowing for a more organic assembly of flowers.

By understanding the characteristics of the Biedermeier design, one gains insight into how it stands out as a style prioritizing organization and neatness, making it the correct answer in this context.
