What design style is known for its unusual use of materials that produces striking and bizarre forms?

The design style referred to in the question is recognized for its innovative approach, emphasizing unconventional materials that lead to unique and impactful forms. This style often strays from traditional aesthetics and utilizes unexpected combinations, which can create striking and sometimes bizarre appearances in floral design. The focus is on creativity and pushing the boundaries of what is typically expected in floral arrangements.

In contrast, the other styles mentioned have more defined characteristics. Classic design tends to adhere to traditional forms and established principles of beauty, often favoring symmetry and proportionality. Romantic design prioritizes softness and lushness, typically evoking feelings of love and beauty in a more conventional sense. Geometric design emphasizes shapes and patterns, generally aligning more with structured configurations rather than the unconventional materials or bizarre forms characteristic of the trained non-realistic style. This unique approach sets the non-realistic design apart, making it the correct answer to the question.
