A rattlebush pod closer up

The last picture, taken in a field in Heavener, Oklahoma, on November 11th, showed a colony of rattlebush, Sesbania vesicaria, that had gone to seed and was drying out. Because that panoramic view included dozens of plants, you couldn’t see what an individual one looked like, nor why the species is also known as bagpod and bladderpod. This photo gives you a better look at one of the “bags” or “bladders” in which the dry seeds rattle around when shaken.

The scattered red in the background was from the ubiquitous sumac, while the yellow near the lower left came from some still-flowering goldenrod.

Sesbania vesicaria Colony Drying Out 8813

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.
