Description

I really love sunflowers and their detail in the flower heads and their petals. Here I shot a macro with a Nikon 105mm macro lens to capture some of that beauty of the flower. I painted the image and added texture to it.

What is usually called the "flower" on a mature sunflower is actually a "flower head" (also known as a "composite flower") of numerous florets (small flowers) crowded together. The outer petal-bearing florets (ray florets) are sterile and can be yellow, red, orange, or other colors. The florets inside the circular head are called disc florets, which mature into seeds


The flower petals within the sunflower's cluster are always in a spiral pattern. Generally, each floret is oriented toward the next by approximately the golden angle, 137.5�, producing a pattern of interconnecting spirals, where the number of left spirals and the number of right spirals are successive Fibonacci numbers. Typically, there are 34 spirals in one direction and 55 in the other; on a very large sunflower there could be 89 in one direction and 144 in the other. This pattern produces the most efficient packing of seeds within the flower head.
