Phlox stolonifera
Phlox stolonifera is a creeping woodland phlox that spreads by leafy stolons to form a soft, semi‑evergreen ground cover. Upright flowering stems rise above the mat in spring with lavender to white blooms. It is best in part shade with humus‑rich, slightly acidic, evenly moist soil and good air movement. Once established it can handle short dry spells and light foot traffic along paths. This species stabilizes slopes, edges shaded borders, and covers ground under open trees.
