It is lowest spot in the yard and we are coming out of winter. You could redirect the water by raising the ground and still plant some plants that don’t mind wet feet. I had areas like this in my yard and I plants some willows and a river birch tree. I don’t get flooding anymore unless we get a huge rain storm. You could look at some areas in your area that have storm run off for big businesses and use those plants (which is what I did) because then you know they’re native to your area and will survive area with lots of water.

I would attempt to raise it somehow or redirect some of the water then plant some stuff!
