Black Lava

Bold, jet-black volcanic rock that makes landscaping pop and never fades, rots, or needs replacing.

Black lava rock brings dramatic, high-contrast color to any landscape — and unlike mulch, it never breaks down, blows away, or needs topping off year after year. Its porous volcanic texture is lightweight for its size, lets water drain right through, and helps the soil underneath hold moisture and stay cooler in Utah’s summer heat.

It’s a favorite for xeriscaping, accent beds, borders, and around trees and shrubs where you want a clean, modern look with almost zero upkeep. Lay it once and it does its job for years.
