Today’s guest star balances the foggy, gray weather in Portland this morning. This sunflower (Helianthus annus) is actually composed of many smaller flowers joined in a single base. The pattern and placement of these florets yield Fibonacci numbersand produce a compact cluster of sunflower seeds (yum!). Sunflowers are native to the Americas, but are now grown elsewhere, where they are used for food, cooking oil, fodder, and as a way to extract uranium, arsenic, and lead from the soil.Check out the National Sunflower Association for a ton of information on these beauties.
