The listing, Black Rod Shoo-Fly seeds has ended.
This is what farmers used to grow around their barns to help keep flyes away, I've grown these for years and do believe it does help BUT you will want to research it yourself to make sure it is safe if animals consume them. Otherwise it is a beautiful bush that gets large (around 6ft or more in height) and loads of flowers. After flowers fade off, it takes on an seed pods that resemble chinese lanterns only tan in color and not orange and the pods are filled with seeds. Does well in zone 3 to 7 after that you will want to look this up and see for your zone. These will even flower when only inches tall...it is an amazing and really pretty plant.
