Geometry of Flowers

Geometry is all around us, hinting at how the universe takes shape. This is no more true than in Spring, when nature bursts onto the scene in a profusion of flowers.

If you look closely, you will begin to notice the patterns: three petals here, five there, a spiral unfurling. Plants can be categorized according to the shape and number of their blooms, and this is not only of value to botanists. There is important information being communicated by these forms. For instance, we can feel assured knowing that all five-petaled flowers produce edible fruit (oranges, apples, and cherries for a start), whereas three- or six-fold plants are often poisonous or reserved for medicinal uses.
