Answer: Fern frond unfurling

What you're looking at

A fern frond unfurling is one of nature's most elegant spirals. You'd normally see these in woodland areas, gardens, and shaded forests around the world. Ferns are ancient plants that have been decorating forest floors for hundreds of millions of years, and their new growth emerges in spring in these distinctive coiled shapes.

When magnified up close, an unfurling fern frond reveals a mesmerising arrangement of tiny leaflets arranged in geometric patterns along a central stem. The spiral structure and the fine texture of the developing leaves create an almost abstract appearance that makes it surprisingly difficult to recognise, even though ferns are familiar to most people in their normal size.

Look for spiral or coiled patterns with fine, delicate textures and a symmetrical arrangement of small repeating elements.
