There are many selections of Moss Phlox, a garden favourite, all of them forming a low mound or cushion smothered by flowers in late spring. This selection, part of the Rocky Road series, produces a showy display of blue periwinkle-coloured flowers. Compared to P. subulata, these are reported to have a more compressed growth habit and spread more slowly in the landscape, especially the first year in the ground. 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.
