Natives that do well along a Sandy riverbank.
I found and cleared a riverbank in a city park, part of it is kind of a dry lawn that nevers get moewed it goes further and further to the river before a steep though shallow slope is caused by the river. Very very sandy and dry. Some willows grow there and I saw a black eyed susan amongst tons of knapweed. It died but I saved the young willow knapweed was attacking. The natives that survived were things like Common milkweed,Vargina creaper common aster, goldenrod and wild grape.
It was very weedy last year when I started filled with invasives. I pulled up all of the knapweed, clover and russian spruge and have planted Ironweed, brown and black eyed suseans, big blue stem, blanket flower, and purple partie clover, coneflowers among others. Today while checking I found the Brown eyed susan was wilting from lack of water, I watered it and saw that the purple parie clover had been damaged slightly. otherwise things look good.
Will these kinds of plants do well at this kind of site?
Also what kinds of natives to northern MN would do well in such a site?
