These are good and not on the invasive and prohibited list in Michigan. I wish beautiful Flowering Rush wasn't on the list, and some of the other beautiful aquatic plants that Michigan deems horrible. I would also like to find a plant that would at least cover the part of lining, that isn't on the list. I need to find flowering plants for the exterior garden area of the pond too but I think I am going to limit the area around it to about seven feet wide.
How sweet of you to search, thanks!
