20 White and Silver Plants Perfect for Creating Moon Gardens
Gardens can be magical at any time of day, but there is something especially magical about gardens as dusk falls, the edges blur and reality recedes the tiniest bit. Isn’t that the time when it’s easiest to believe in fairies, magic and another dimension just beyond our senses? For many of us, first thing in the morning and late in the day is when we most often have time to spend in our gardens. As the light dims, the colors of the rainbow start to recede. However, as the moon rises, white flowers and silver foliage take central stage, seeming to glow with otherworldly light. If you haven’t considered the joys of a white garden before, now might be the perfect time to add some white to your garden or even transform a portion of your garden into an all-white and silver moon garden.
Diamond Snow and Diamond Frost are perfect to kick off our list of white plants. These plants are as close to indestructible as you can get with a living plant. They love heat, don't mind some drought stress, bloom non-stop, don’t need to be deadheaded and will grow merrily all season with on application of controlled release plant food. Diamond Snow has double flowers (they’re actually bracts, but we all call them flowers), a dense habit and creates a chunk of color when planted in combination recipes. Diamond Frost is a champion weaver and mingler, mixing in with the other components to create a wonderful combination of textures and colors.
Best in Part Sun to Sun, but can tolerate shade. 12-18” tall. Annual.
If you love the look of Diamond Frost but would like a large plant that can hold its own in the landscape, Diamond Mountain is the perfect plant to use. Diamond Mountain is a super-sized version of Diamond Frost, often twice the size of Diamond Frost. This extra size lends great presence for landscape plantings.

When we are choosing plants for Proven Winners the most important criteria was have is that the plant bloom well through the summer for home gardeners.
