Motherwort is a square-stemmed mint family perennial with deeply lobed leaves and whorls of small pink-purple flowers that bees adore. Traditional Western and Chinese herbalism leans on aerial parts for "calm the heck down" teas—pregnancy warnings apply; read real references, not blog astrology. Often short-lived in brutal wet summers unless given airflow and leaner soil; behaves more reliably in cooler temperate zones along the Eastern Seaboard. ☀️💧 Sun and Water Requirements: Full sun to light shade; average to moist, well-drained soil; tolerates poor ground and city margins—classic "grows by the dumpster" resilience. ✂️ Propagation: Seeds (cold stratify for best germination); division in spring or fall; self-sows politely to obnoxiously depending on mulch depth. 🌾 Harvest / Best Use Timing: Cut aerial parts for tea and tincture when flowering peaks; harvest often or it gentrifies the fence line.
