Canna Lily

Canna Lily

“Mathematics is the language of nature.” ~Galileo

This is a picture of a canna lily leaf in my backyard.  They are hearty plants and are easy to grow. In fact they multiply over the years so you can dig up the bulbs, separate them, and replant them elsewhere in the garden.  This beautiful spiral caught my eye as well as the striking patterns and colors on the broad, green leaves.  Fibonacci spirals are found in many places in nature. Think seashells and the spiral shape of the galaxy.  Fibonacci spirals are formed following the Fibonacci sequence, where each number is the sum of the two preceding numbers.  Fibonacci numbers like 3, 5, 8 can be seen in flower petals, tree branches, and spirals found on pineapples, pine cones and other natural phenomena.  Have you ever noticed that before?  It’s super cool.  Math is everywhere!

Check out some of these examples:
