La successione di Fibonacci è onnipresente in natura. Quasi tutti i fiori hanno tre o cinque o otto o tredici o ventuno o trentaquattro o cinquantacinque o ottantanove petali: i gigli ne hanno tre, i ranuncoli cinque, il delphinium spessone ha otto, la calendula tredici, l'astro ventuno, e le margherite di solito ne hanno trentaquattro o cinquantacinque o ottantanove. Troviamo i numeri di Fibonacci anche nei fiori di girasole. Le piccole infiorescenze al centro di girasole, che poi si trasformano in semi, sono disposte lungo due insiemi di spirali che girano rispettivamente in senso orario e antiorario. Spesso le spirali orientate in senso orario sono trentaquattro e quelle orientate in senso antiorario cinquantacinque; ma a volta sono rispettivamente cinquantacinque e ottantanove, o addirittura ottantanove e centoquarantaquattro, e si tratta sempre di numeri di Fibonacci consecutivi (il cui rapporto si approssima alla sezione aurea).
