Rattlebush colony drying out
Another thing I encountered in a field in Heavener, Oklahoma, on November 11th was a colony of rattlebush that had gone to seed and dried out. I didn’t know what species it was, but in checking species distributions later I concluded it must have been Sesbania vesicaria. The common names rattlebush and rattlebox come from the fact that the drying seeds end up loose inside their pods and really do rattle around when the pods are shaken.
