Dogwood Time

Straight out from my bedroom window, in our dogwood tree, a little robin sang, “Winter’s over. We survived another one!”


Did you know that the Pacific dogwood is the provincial flower for the province of British Columbia? Its flowers have four to six petals. That in itself is unusual, as probably the most common number of petals for flowers is five.

While researching the number of petals on a dogwood, I came across the term “Fibonacci Numbers.” The number of petals on most flowers is one of the Fibonacci numbers, but the dogwood only sometimes complies. The Fibonacci number sequence is named for Leonardo of Pisa, also known as Fibonacci, for introducing the concept of these numbers to the western world in the early 1200s.

The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 …

Can you guess what the next number is going to be?

I was amazed at how it works. The next number is always the sum of the previous two.

I think someone used this sequence to figure out the rate at which rabbits breed. I think, too, that Fibonacci must have done his research in my backyard.

Math and nature are so connected, it never ceases to amaze me.
