description_en: Genus of 67 species of evergreen or herbaceous, low-growing or cushion-forming to erect perennials, as well as a few annuals and shrubs, found mostly in North America (one from Siberia, Russia). They are grown for their showy flowers, borne mainly in terminal corymbs or panicle-like cymes, some-times singly. The flowers are salverform, occasionally funnel-shaped, each with a narrow, tubular base opening to 5 flat, ovate petal lobes, sometimes in a star-shaped arrangement. Leaves are simple, entire, linear to ovate, light to dark green, and often in opposite pairs, the upper leaves sometimes alternate. Mat-and cushion-forming species, from dry, rocky habitats, flower in spring or early summer; grow in a rock garden or alpine house, in a dry wall, or as edging. Woodland species are mainly trailing, and usually flower in early summer; grow in shady sites. The taller "border" phlox are mostly from moist riverside habitats, and produce large corymbs of flowers, usually in midsummer, which are good for cutting. Annuals, from dry rocky slopes and coastal sands, flower from late spring to autumn, and are useful for bedding.

hardiness_en: Fully hardy to half hardy.

cultivation_en:

propagation_en: Sow seed of annuals at 13-18°C (55-64°F) in early spring; sow seed of perennials in containers in a cold frame when ripe or in spring. Divide P. carolina, P. maculata, and P. paniculata, and their cultivars, in autumn or spring. Insert basal cuttings in spring, or take root cuttings in early autumn or winter. Take softwood cuttings of non-flowering stems of cushion-forming perennials in spring. Detach rooted pieces of stem from trailing perennials in spring or early autumn.

pests_en: Susceptible to leafy gall, stem eelworms, powdery mildew, and leaf spot.
