Description: A lightweight, porous volcanic rock characterized by its striking deep red to reddish-brown color and irregular, angular shapes. Available in various sizes (e.g., 3/4" - 1 1/2"), it helps retain soil moisture and provides some insulation.  
Used for: Eye-catching ground cover in landscape beds (especially effective against green foliage), pathways, rock gardens, around succulents or desert-themed landscapes, and sometimes in gas fire pits (verify suitability for high heat).
