Found this story and thought I would post it here.

                    DENVER — Strange forests with some features of today’s tropical trees once grew in Antarctica, new research finds.

Some 250 million years ago, during the late Permian and early Triassic, the world was a greenhouse, much hotter than it is today. Forests carpeted a non-icy Antarctic. But Antarctica was still at a high latitude, meaning that just as today, the land is bathed in round-the-clock darkness during winter and 24/7 light in the summer.

The question, said Patricia Ryberg, a postdoctoral researcher at the University of Kansas Biodiversity Institute, is how plants coped with photosynthesizing constantly for part of the year and then not at all when the winter sun set.

“The trees are the best way to figure this out, because trees record physiological responses” in their rings, Ryberg told LiveScience.

A forest mystery”

An interesting view of a different environment than mine own.
