I got river rock at stone yard. Beautiful colors in the small netted bags...small stones. The bigger stuff not as colored and at two yards I went to, the rock was sold by size. So, I could not get a large amount of mixed sizes
I have used sparkling glass mulch and that looks real pretty. Landscape fabric laid first so it would not sink...then topped with the mulch. Stays great for years ( so far ) hose it off if it starts looking a wee bit dusty / dull. Would look pretty near water. Got that at county landfill.... They crush their own...sold by the scoop...a big machine sized scoop...carried it off in the pickup bed.
