Growing by the side of the road in Birch forest
In an open, sunny area of the feral part of our yard which is surrounded by mature boreal forest.
These are plants that were growing next to a water retention lake in Fairbanks where the permafrost melted. I am told that they might have been dormant for 30,000 years in the permafrost and now grow again early in the season and are different from the other plants around. I found one study that revived a plant from fruit tissue see https://www.newscientist.com/article/dn21498-plant-blooms-after-30000-years-in-permafrost/.
