Silver torch thrives in conditions that mimic its native high-altitude habitat. Key care points include ample sunlight and a well-draining potting mix to prevent root rot. Silver torch requires minimal watering, allowing the soil to dry between waterings, and is tolerant of cooler temperatures, though it should be protected from frost. Special care should be taken during the winter months, when watering should be reduced to prevent cold damage.
