I’ve spent years experimenting with every ground cover and mulch under the sun, but nothing excites me like the texture and drama of lava rock landscaping. Let me share twenty of my favorite—and sometimes unexpected—ways to use this volcanic wonder in your own outdoor space.
Add Drama With Contrasting Color Bands
A lesson from a bold client: alternate strips of red and black lava rock as bands through a garden bed for a graphic, modern look. The color contrast stops visitors in their tracks every time.

After years of re-mulching with bark, I finally tried lava rock mulch around my perennials—and haven’t looked back. It suppresses weeds, retains moisture, and never fades, giving my beds a permanent, polished look.
