Where Fibonacci Numbers Appear in Nature

The Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, 21...) appears frequently in natural patterns. These numbers describe patterns such as spiral arrangements in pine cones, spiral galaxies, and spiral patterns in flower petals.

Each square represents a Fibonacci number, with sizes growing according to the Fibonacci sequence. Click on any square to see its Fibonacci value.

• Pine cones often show Fibonacci spiral patterns (e.g., 5 and 8 spiral lines)
• Some flower petals follow Fibonacci numbers (e.g., 5 petals in many flowers)
• Seed patterns in sunflower heads follow Fibonacci spiral patterns
