Description

Phlox carolina is a sturdy species with robust, erect stems that are often streaked with purple. The flowers are vivid, ranging in color from pink to almost purple, and borne in dense, rounded terminal clusters. It usually grows to a height of 2 to 3', but on occasion will reach 4' or more under very favorable conditions. The leaves are oval, bright green, and leathery hence the common name thickleaf phlox. This species is evergreen in the warmer parts of its range.

Cultivation

Easy to grow, and low maintenance, this species is among the most resistant to powdery mildew of any phlox. Native to moist forest clearings and wet meadows, it is very tolerant of wet feet, but will adapt to more typical garden conditions with moist, well-drained soil. It enjoys a blooming period of 2 to 3 months, beginning in early summer and extending intermittently until frost. It will slowly spread vegetatively to form large clumps, and is does not self-seed aggressively. Zones 5-9

Propagation

Propagate from seed, division, or cuttings.
