They remain unable to grow in ice sheets. Or those in low grow period zones, where the tree will maintain it’s production through winter and even in a no-grow tile, such as the northernmost tundra tiles. They have a high potential in making difficult games possible, such as those in the extreme desert, where there is no arable land for plants, but plenty of sand for the tree. The Gauranlen trees will continue to support their dryads year-round, and are only affected by connection strength. They can grow on a wide variety of tiles and heal themselves over time. Gauranlen trees boast unprecedented hardiness compared to all other plants.
