Enhance your landscape with the natural elegance of Greenbrae Gray — a premium 1" to 3" smooth river rock named after the scenic town of Greenbrae in Marin County. This hand-selected river stone features a calming blend of soft grays, coastal blue undertones, and subtle earthy highlights, offering a clean, timeless look for both modern and rustic outdoor designs.
 
Ideal for homes and commercial properties throughout San Rafael, Petaluma, Napa, Santa Rosa, and Vallejo, Greenbrae Gray brings natural sophistication to any project. Its rounded edges make it safe for walking surfaces, yet its weight and size keep it in place during heavy rains or irrigation.

Tree rings, garden borders, and shrub accents in Fairfield and Glen Ellen
Decorative rock mulch alternative in front yards and medians
