General Culture:
Best grown in dry, sandy, well-drained soils in full sun. Tolerates somewhat wide range of soils, however, as long as drainage is good. Root rot commonly occurs in wet or poorly drained soils. Intolerant of the high summer heat and humidity of the deep South. Spreads by runners to fill in areas, but is not considered to be invasive. Shear off flower stems after bloom or mow on high setting. Plant 9-12" apart to cover large areas.
Noteworthy Characteristics:
This snow-in-summer cultivar is a short-lived, low-growing, mat-forming perennial which is typically massed in sunny locations as a ground cover. In late spring, flower stems rise above the foliage mat (typically to 10") carrying clusters (cymes) of white blooms which form a snow-like carpet (hence the common name). Flowers (to 1" diameter) have 5 notched petals and are similar in appearance and closely related (same genus) to several of the chickweeds. When not if flower, tufts of narrow, silver-gray leaves form a 6" tall foliage mat which is more compact, slower spreading and less invasive than the species.
No serious insect or disease problems. Root rot can be a serious problem, however, if plants are grown in poorly drained soils or in soils that remain wet. Plants are short-lived, and dead patches often begin to appear after several years. In St. Louis, the foliage usually becomes less attractive as the summer progresses.
Uses:
Ground cover for sunny areas. Rock gardens, border fronts, edgings, bulb cover or dry stone wall planting pockets.
