Phyllotaxis 🌿🌻🌀

Phyllotaxis are spirals found in plants originally observed (by Modern times) by Leonardo DaVinci. Later it was observed as Fibonacci sequence in 1837.

Phyyllotaxis essentially is the organization of plant organs.

Plants can be broadly classified into two main categories based on their arrangement of leaves:

spiral phyllotaxis, characterized by a consistent divergence angle between successive organs,

and whorled phyllotaxis, where multiple organs occur at the same level along the stem.

but here are some more striking examples

Pine Cones and the Fibonacci Sequence

Pine Cones and the Fibonacci Sequence

While we’re on the topic of pine cones, have you ever considered their scales and the spirals they form? Nature is replete with spirals, so perhaps it’s no surprise that they are found in pine cones. The more interesting thing is that the number of spirals found on pine cones are almost always Fibonacci numbers. But maybe that’s not that surprising either, as Fibonacci numbers are also pretty…

Welp – this guy’s leaves are in fact NOT distichous.

in the past few weeks the leaves went from growing opposite of each other on their stem, to slowlyyy starting to form a whorl. oh well! i love him all the same. ¯\_(ツ)_/¯
