Here in Minnesota, L. michiganense is fairly common. That is to say, I know of several places, particularly along railroad right-of-ways, where patches of michiganense can still be found. Quite a few years ago, I rescued a couple of bulbs just ahead of the bulldozer. Initially, they thrived and I ended up with two impressive clumps in different parts of my yard. I have never seen stems this tall in the wild.
Above photo taken in 2002, don't know if it will reproduce very well here. Unfortunately both clumps soon after this glorious success began diminishing and I lost both of them. I have no idea why, but it is still my biggest disappointment in gardening.
I also purchased a couple of bulbs, which did not do well at all. One of them still comes up though, and I see maybe one bloom every 2 or 3 years.
