I do not have the specific information whether Brazils Anthracite Black Phyllite can be used in landscaping or not. However, phyllite is typically a high-grade metamorphic rock that is resistant to weathering and erosion, making it a suitable material for various applications such as tiling, roofing, and wall cladding. In landscaping, it may be used for features such as garden walls, rock steps, and even as a decorative rock. It is always recommended to consult with a professional landscaper or geologist to determine the suitability of specific rocks for landscaping purposes.
