Part of Hibiscus trionum petals have a wrinkled cuticle that creates a visual signal perceived by pollinators. These wrinkles are ordered nanostructures capable of scattering light. They develop from the cuticle on epidermal cells and maintain their orientation across several cells, forming tissue-wide patterns. Our experiments demonstrate that they result from mechanical instabilities rather than from the guided deposition of material secreted by the cell. We have performed a detailed characterization of Hibiscus trionum petal development and the mechanical properties of its cuticle to understand how a buckling process produces these microscopic ordered structures.
