Bring a natural, timeless look to your landscape with Sierra Blend River Rock, a versatile decorative rock sourced straight from Northern California streams. These smooth, rounded stones come in a variety of neutral earth tones — soft greys, cool blues, warm tans, and subtle browns — making them perfect for water-wise gardens, dry creek beds, border accents, and modern curb appeal upgrades.
 
Available in three size options for different design needs:
1.5" – Ideal for general ground cover, flower bed accents, and pathways.
2"x4" – A bolder choice for dry riverbeds, edging, and decorative highlights.
4"x8" – Excellent for accent boulders, water features, riverbeds, borders and erosion control.
 
Whether you're landscaping a home in Napa Valley, refreshing a front yard in San Rafael, or designing a commercial planter bed in Fairfield or Petaluma — Sierra Blend river-rock brings texture, contrast, and a polished natural aesthetic that blends with any style.
