We get more than 360 days of sun in the desert, so we don’t often have gray skies—but there are some great gray- or silver-leafed plants that can jazz up our potted winter bouquets.
Almost any color scheme has space for silver. It is a contrasting color that plays a supporting role to bright jewel-tone colors, and it makes pastels pop more than they might on their own. Silver can also look like dew drops in the winter morning sun. Most silver-leafed plants can take our sun and will also thrive in the shade. I especially enjoy using gray foliage with shades of blue and purple.
Readily accessible gray or silver-leafed plants include the dusty miller; the gopher plant; and lamb’s ear. These plants not only have stunning appearances; many are also drought-tolerant.
One of my favorites is artemisia, which is a perennial of the Asteraceae family. Valued for its beautiful, slender, gray-to-silver leaves on tall arching stems or low mounds, it is pleasantly soft to the touch and critter-resistant, and it responds well to pruning.
With its soft, silvery leaves, dusty miller is typically grown as an annual foliage plant—despite the fact that it’s actually a perennial that will flower after the first year.
Your typical bedding plant of dusty miller has yellow flowers. I do not let mine complete the flowering process, because it weakens the plant in our desert heat. However, in recent years, I have found another variety of dusty miller, Velvet Centaurea, that has beautiful artichoke-like purple flowers.
Since the dusty miller truly is a perennial, you might want to see how long you can maintain it in your potted garden. Trim it to shape, and enjoy the role it plays with your flowers.
