Ask any 4-year-old what color leaves are, and they’ll confidently proclaim, “Green!” And green leaves are just fine, for the most part. We expect gardens to be basically green, from the verdant lawn to the tops of the trees (at least during the growing season). When it comes to plants, that glowing, chlorophyll-derived green implies life and health.
But one can have too much of a good thing. That’s why our landscaping includes plants with leaves that are a soft silver (that sounds much better than “gray”). No, I don’t want an entire yard full of them, but as accent plants, silvery leaves can make quite the impression.
