repetition in nature

If you squint at this image long enough you may, like me, start to see a wire-frame sculpture of a saguaro cactus. Lowly motherwort and the majestic saguaro cactus?  Sure. Nature repeats simple forms all the time. And lets not forget to take note of what looks like the always beautiful Fibonacci spacing of those calyx (calyces?).  Simple motherwort revealing the secrets of the universe.
