Snow-in-summer is a flowering perennial that grows as a mound of silver-grey leaves. In late May, small white flowers cover the plant. Snow-in-summer is an easy care groundcover that will spread through underground stems if growing conditions are ideal. Its light-colored leaves contrast nicely with other landscape plants.
Snow-in-summer needs regular moisture and good drainage. It can grow well in sandy soil if watered periodically.
Snow-in-summer has performed well at the Xeriscape Garden where it has received regular water. The white flowers are very pleasing.
In very low water zones, it has faded out over time. Partridge feather, a similar-looking groundcover with light grey leaves, has performed better with little supplemental irrigation.
After the blossoms have faded, shear off the flowering stems to highlight the beautiful leaves for the rest of the growing season.
