Swamp Sunflowers

It seems most flowers that bloom in Autumn are yellow, especially the Native ones. There is one blooming now ( yellow) that is the greatest. It is Swamp Sunflowers. They can get 8 feet tall. They spread underground. That is why many people do not want them. If you start early, you can pull all the unwanted ones. Most do not know that you can trim them up till July. That can make you have an enormous showing in the fall. I like to start low and do it in layers to get the most results.
