Stevia rebaudiana is the small aster-family herb whose leaves taste sweet without sugar—glycosides do the trick, bitterness shows up if you overdo concentration or harvest late. Grow as tender perennial with mulch in 9b+; colder pockets treat as annual or overwinter cuttings indoors. Intense summer rain can beat up leaves—give drainage. ☀️💧 Sun and Water Requirements: Full sun to light afternoon shade in brutal heat; light fertile soil, steady moisture, never soggy. ✂️ Propagation: Soft cuttings root easily; seed germination is moody and variable. 🌾 Harvest / Best Use Timing: Pick leaves steadily before heavy flowering for the mildest sweetness; remove flowering stems if you want more leaf than bitterness.
