1. A recent genetic study -which I forgot to save- points to the sunflower
being domesticated in a river environment in eastern North America. The
probable location is what is today Arkansas. The new study points to a
single site of domestication. The alternative theories have the
sunflower being domesticated in Mexico and spreading north or being
domesticated twice: once in Mexico and once in the eastern US.
Arkansas' state flower though is the apple blossom. Maybe Arkansas should switch to its homegrown glory, the sunflower!

Sunflowers have been shown to absorb radioactive cesium from the soil.
They were planted around Chernobyl and now 10,000s are being planted
around Fukashima, Japan.
