Not sure what you mean by "nitrogen based soil". Can you explain that a bit?

There is one plant family that I heard of which will take up excessive nitrogen from the soil until their plant tissues nitrogen reach intoxicating level and become unsuitable for human and animal consumption ----- Amaranth.

It sounds like you're looking for acidic soil loving plants given the plants you listed.

You can do a quick web search and get many lists of plants.

Soils in Minnesota tend to be acidic, a low soil pH, but since Nitrogen is fairly volatile I would not think that would be the soil problem you are thinking. Linked below is a list from Purdue and I am sure your University of Minnesota Cooperative Extension Service would have that information as well.

Here is a link that might be useful: Plants for acidic soils

Thank you for the input. I didn't realize nitrogen soil is the same as acidic soil. I had done a google search for nitrogen soil with few results. Using acidic soil is what I needed to do. Happy gardening.

First time I ever heard of acidic soils referred to as "nitrogen based" or "nitrogen soils".

Until I got to TX all of soils I dealt with were acidic, and liming was a periodic exercise. The calcareous clay here was a new experience.

"so how do soils in MN wind up being mostly acidic?"

It's mostly a property of northern MN soils because of a mix of historical geology + common plants. A huge chunk of northern MN used to be underwater lake land and a lot of the plants/trees common up there are evergreen pines and similar.

In Western and Southern MN, it's not uncommon to find soils closer to neutral or alkaline.

Most any soil scientist will tell you that the soils in Minnesota are acidic because of the amount of rain they receive each year. As a general rule soils east of the Mississippi tend to be acidic while those westward tend to be alkaline, all due to the amount of rainfall.

"... all due to the amount of rainfall."

While rainfall contributes to the result, it is not the most significant determinant of soil pH. Most soil scientists will tell you that the geological origin and the attendant soil texture along with marine sediment incorporated into the soil is more significant than rainfall.

"What plants (flowers) like nitrogen based soil?"

When soils are high in nitrogen, such as those amended heavily with manures, they will grow leaves well, but may not flower well or, over time, be as healthy as they would be in a more balanced soil. One fall I mulched with what was supposed to be well-aged manure. Over the next several years the leaves on the Lady's Mantle plants grew huge and flopped over and my hydrangea in that bed did not flower well. Only now, 3 years later, are the plants beginning to look more 'normal' altho the Lady's Mantle leaves are still larger than those of other LM plants in other areas of my garden. Obviously, to me, I applied too much of the old manure and it created an unbalanced soil high in nitrogen.

From everything I've read high nitrogen is not the same as normal soil acidity altho perhaps high nitrogen might lead to acidity until it leached/gassed out and the soil reverted to it's normal pH.
