Only a few sunflowers were grown in 2009, but those that grew were huge! Each “flower” is actually a head inflorescence, composed of many small flowers. The yellow pieces that compose the flat surface in the center of the sunflower are considered individual flowers, known as disk flowers.
What most people consider the “petals” of the sunflower, are actually called ray flowers and each petal represents an individual flower. Each disk floret turns into one seed. And if the head of the sunflower is ever missing any seeds (noticed by gaps or holes in the head) it indicates improper or incomplete pollination. The seeds of these sunflowers were harvested and will be used this upcoming year. Photos taken by Quentin Koopman.
