Wild Healroot is Xerigium
Renames wild healroot to Xerigium, and changes the sprite to an AI upscaled version of the original healroot sprite. It's not perfect, but it's much better than the original texture when you zoom in. Also adjusts the scale slighlty to suit the different sprite. Everything is done through patch operations, so it should work from Alpha 17 to Rimworld 2.7.
