You know you have rock gardeners on your hands if the garden tour ends up (and stalls) in the nursery area. Aside from the rather obvious plants and rocks, a rock gardener’s garden is likely to have bins, buckets, and barrels (tucked somewhat out of sight) filled with various grades of gravel, sand, soil, and compost. If the hypothetical tour stumbles on this stash, you can be sure it will linger there for a very long time as well. Everyone wants to know what your seed mix is, where you got your nifty gravel top dressing and where you found that marvelous rock mulch? Sometimes I think our ilk cares more about the mineral content in our gardens than the chlorophyllic.
