Try growing lupins, shasta daisies, echinacea, and black eyed susans. I'm doing this in my acre to make the view stunning and they are easy to do. I started some in small pots and I seeded some in late fall by tossing seeds on to bits of earth that was visible. The lupins have come up easily fighting for space. The others didn't germinate as well but I'm put in my potted plants and they are doing fine. All of them spread by seed. I know the deer wont eat them. This fall I'm going to try poppies, bachelore buttons, and annual chrysanthemums. I don't know if the deer will eat them. They have eaten all my hosta, day lillies, and all the heads off my calendulas. I plant corn and other things like peas and pole beans far from my "garden". I plant all the extra fruit and veg with the corn.
Herbs are useful weeds. Most of them will work in your field. Put your invasive herbs in large pots {childrens wading pools with holes drilled in the bottom will hold a lot of plants.}
Good luck.
