Noteworthy Characteristics: There are many selections of Moss Phlox, all of them forming a low mound or cushion of dark green needle-like leaves, smothered by tiny flowers in late spring. This variety produces a showy display of large snow-white flowers. Clip plants lightly immediately after blooming to encourage a dense habit. Wonderful in the sunny rock garden, for edging, or in mixed containers. Clumps may be ripped apart and divided in early fall, after 3 to 4 years. Requires good drainage. Drought tolerant, once established. Grows to 2 to 6 inches tall and 12 to 18 inches wide. Zones 2 to 9.
