What characterizes a linear arrangement?

A linear arrangement in floral design is specifically characterized by its emphasis on lines and shapes created through the placement of flowers and foliage. This type of arrangement often features flowers arranged in a way that highlights the movement and directionality, drawing the eye along lines that can vary in both height and depth. The use of lines gives the arrangement a structured and dynamic appearance, emphasizing form and contour rather than fullness.

The other options describe characteristics that do not align with the principles of linear arrangements. For instance, arrangements that are wide and flat are more suggestive of a specific type of design that focuses on spreading rather than lines. A circular pattern defines a different stylistic approach, which centers on creating a round or spherical look rather than focusing on linearity. Likewise, lacking height may imply a focus on low, full arrangements, which contrasts with the potential for varying vertical elements inherent in linear designs. Therefore, the emphasis on lines and shapes with flowers is a distinctive feature of linear arrangements that sets them apart in floral design.
