Stand next to a full-grown sunflower in July and it looks back at you from higher up. The stalk is rough, the leaves are as wide as your hand, and the face is a brown disc ringed in yellow. Most kids go quiet for a second, then ask if they can pick one.
A sunflower is a good first flower to color, for a simple reason. It hands you most of its colors already: yellow petals, a brown middle, a green stalk. A three-year-old can finish one and feel proud. Yet there is more tucked inside that brown middle than it lets on, and an older child who slows down will find it.

The face is doing math
Look closely at the center and the seeds are not scattered around. They sit in two sets of curving lines that spiral out from the middle and cross each other, one set winding left, the other right. Count the spirals each way and you usually land on numbers like 34 and 55, neighbors in the Fibonacci sequence.
That slow, looping pull is the same thing that keeps people coloring mandalas. A sunflower's face is a mandala the garden grew on its own.
