The cultural concept, visual aesthetic, and naming inspiration of the koru are based entirely on the natural growth cycle of the endemic New Zealand silver fern (Cyathea dealbata). When the fern produces a new frond, it emerges tightly coiled in a symmetrical spiral before unfurling toward the light. This natural biological phenomenon inspired indigenous Māori carvers and weavers to adopt the shape as a foundational motif representing creation and organic expansion.
