This cultivar of the popular blue phlox has round, full flowers with overlapping petals. It is noteworthy for its particularly rich blue-violet color. Use it in rock gardens or alpine houses, in a dry wall, or as edging.

This is a very fragrant native woodland phlox with powder-blue flowers in spring. Reaching only 1 foot tall, it can spread to almost 2 feet and makes an attractive groundcover under shrubs or planted with other spring-blooming wildflowers. Leaves are semi-evergreen and hairy; stems root along their length. The blue flowers are salverform with petal lobes. This plant attracts hummingbirds and butterflies.

From late spring to early summer, this species bears pendent, green-tipped white flowers along arching stems. These mature into spherical black fruit in autumn, when the foliage turns yellow.

Moss phlox is a dense ground cover blanketed with notch-petaled flowers in April and May. Blooms can be muddy hot pink, bright rose, and magenta, while other cultivars include white, soft lavender-blue, clear pale pink to deep pink, clear scarlet, and lavender, some with a darker or lighter eye. Evergreen foliage is narrow, short, and stiff. Darker-flowered forms have dark-green leaves or red-tinged leaves that darken to burgundy in winter.
