I’m late for this week’s Sunday Stamps as I am traveling (work) and forgot to autopost.
This week’s theme, “patterns,” is beautifully exemplified by the Finnish Post Office’s 2011 series of glow-in-the-dark stamps featuring the (illustrated) dahlia flowers. Known for their annual tradition of crafting unique stamp designs, the Finnish Post Office’s choice of the dahlia flower is a nod to the intricate patterns found in nature and inviting us to take a closer look at the everyday wonders around us.
The dahlia, native to North America and Mexico, was introduced to Europe in the 16th century and has since captivated flower enthusiasts with its geometric beauty. The stamp design showcases two radiant dahlias set against a dark background.
Dahlias symmetrical patterns are a testament to the mathematical precision in nature’s creations. The petals of a dahlia follow a fascinating sequence that aligns with Fibonacci numbers, a series where each number is the sum of the two preceding ones. This sequence creates a spiral pattern that can be seen in the arrangement of seeds, fruits, and flowers, including dahlias. This natural occurrence of patterns is not only aesthetically pleasing but also serves as an inspiration for artists and designers in various fields.
