The huge, fiery blooms of the Helianthus annuus (sunflower) are actually inflorescences comprised of 1,000–2,000 individual florets clustered together in a spiral pattern.

“Generally, each floret is oriented toward the next by approximately the golden angle, 137.5°, producing a pattern of interconnecting spirals, where the number of left spirals and the number of right spirals are successive Fibonacci numbers. … This pattern produces the most efficient packing of seeds within the flower head.” (from the Wikipedia article, Sunflower) 

I photographed this lovely bloom a few days ago, outside the School of Divine Energy Medicine in upper Willis Street, Wellington.
