Most of the plants are bog and wet soil loving plants..the circle is Acorus gramineus ogon (yellow circle) the light green is variegated Acorus gramineus..both are sweet flag but not the native variety.
on the edges are Cinnamon fern,Astilbe,Ligularia Brit Marie, and orange daylily that was on the site.
The clump in the middle is Hybiscus mosheutos fantasia.
This project is mucky wet all the time.
