Primary Colored Trees and their respective saplings, Rainbow colored Grass, and almost every plank related block for each tree (no signs or boats).
Trees have no issue growing in the overworld, but if the sapling is placed anywhere the tree couldn't possibly grow, it'll pop off the ground when it tries to grow. (they only pop before v2, in v2 they stay saplings just like other trees)
Recommended to use Every Compat (Wood Good) and almost any other wood related mods for Furniture and such, was very surprised to see this works with Double Slabs so you could easily mix glowing planks into your floors and walls for truly unique lighting. If I ever learn shaders, this mod will become beautiful.
