Contiene saponine, concentrate nel tubero/radici; l'ingestione causa vomito e quantità elevate possono causare problemi del ritmo cardiaco e crisi.
Una pianta tuberosa che fiorisce in inverno con foglie a forma di cuore marmorizzate e fiori simili a navetta in bianco, rosa o rosso.
Bright, indirect light; avoid hot direct sun. Good light keeps flowering going through the cool season.
Keep the soil lightly moist while in leaf and flower, watering from below to keep the crown/tuber dry (the top of the tuber rots easily). Reduce as leaves yellow and let the tuber rest nearly dry in summer dormancy.
Free-draining, humus-rich mix; plant with the top of the tuber slightly exposed.
COOL-loving, 10–16 °C; hot rooms (above ~20 °C) trigger early dormancy and collapse. Average humidity.
Feed every 2–4 weeks while in active growth/flower with a low-nitrogen, higher-potassium fertilizer.
Twist off (do not cut) spent flowers and yellow leaves at the base. Toxic to pets and people — the tuber is the most poisonous part (saponins).
