First looking at trees, we will now examine the branching structure of secondary branches growing off the trunk. “Some plants express the Fibonacci sequence in their growth points, the places where tree branches form or split. One trunk grows until it produces a branch, resulting in two growth points. The main trunk then produces another branch, resulting in three growth points. Then the trunk and the first branch produce two more growth points, bringing the total to five.”

By drawing straight lines through the branching points, the pattern can be easily seen.

Kate RussellThat was fascinating! I always knew plants were interesting, but you’ve shown me how to take it to an entirely new level!

luis fonsecaQuite interesting how things happen in nature. And the importance of rabbits to number theory. Thank you for helping us see things in different ways.

Michael ConleyFascinating. Thanks for sharing!
