From the abstract:

"Here, we show that the circadian clock controls the timing of late-stage floret development, or anthesis, in domesticated sunflowers. In these plants, up to thousands of individual florets are tightly packed onto a capitulum disk. While early floret development occurs continuously across capitula to generate iconic spiral phyllotaxy, during anthesis floret development occurs in discrete ring-like pseudowhorls with up to hundreds of florets undergoing simultaneous maturation. "

That's so interesting.

The United States are not the largest producers of sunflowers, and yet even here over 1.7 million acres were planted in 2014 and probably more each year since. Much of which can be found in North Dakota.
