The Garou can cause plants to take root and grow in places where it is usually impossible for plants to grow. This Gift does not make plants grow supernaturally fast; it simply gives them a chance for life where none existed before. The plants must still be tended to and watered. However, the plants can use artificial substances such as concrete and plastic for soil. They dig their roots in and grow. Plants can even be coaxed to grow out of walls, as long as they are nurtured during the process. This Gift is taught by plant spirits.
The Garou must plant seeds in the area to be fertilized. If this is a concrete wall, he must place the seeds in cracks within the surface. He then rolls Charisma + Science (or Herbology) against a difficulty dependent on the toxicity of the area. An abandoned lot might be 5, a typical city building bathed in the smog of passing cars might be 6 or 7, while an oil spill site might he 9.
