What floral design technique is known for creating arrangements that are compact and rounded in shape?

The Biedermeier design is characterized by its compact and rounded shape, often resembling a tightly arranged bouquet. This style emerged in the 19th century and is known for its circular form, which typically layers flowers in a structured manner. The Biedermeier design often features a mix of different flowers and foliage, arranged in a way that creates a visually pleasing, harmonized look. The technique emphasizes symmetry and simplicity, focusing on creating an elegant yet unobtrusive presentation.

Mound design, while also creating compact arrangements, tends to form a more generalized mound shape without the layered structure seen in Biedermeier. Structural design emphasizes angles and lines rather than roundness. Symmetrical design focuses on balanced proportions but doesn't necessarily conform to the rounded, compact characteristics of the Biedermeier style. Each of these alternatives presents distinct design principles and visual outcomes, but the rounded shape defining the Biedermeier is what sets it apart in this context.
