Rainbow boulders

Rainbow is a colorful boulder. It is rhyolite, though at first glance it looks like a multicolored sandstone. Streaks of yellow, purple, white and pink run through each piece. If most boulders are background, this one is the feature. A single Rainbow boulder can carry a whole planting bed.

Yellow, purple, white and pink

The colors appear as streaks, so every side of a boulder looks different. Walk around each piece before you choose, and decide which face you want pointing toward the house or the street.

Wetting the stone brings the streaks out. Ask staff to hose one down so you can see the full color.

A boulder to feature

Use Rainbow where it will be noticed: near the front door, at a bend in a path, beside a patio or as the high point of a rock garden. Keep the stone around it plain so the colors can lead.

The purple and pink tones pair nicely with lavender, sage and other flowering plants. More layout ideas are on our boulder landscaping page.

Sizes and buying

Boulders range from pieces you can lift to pieces that need a machine. All are sold by weight. Sizes on hand change with each load, so call (916) 363-4239 before you visit.

Staff can arrange delivery and refer you to a crane placement company for the largest boulders.
