silver torch · Cleistocactus strausii
Also known as: silver torch cactus
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.
Silver torch is a heliophilic plant and needs sufficient sunlight for its growth and blooming. It can be placed on the outdoor balcony or in the garden without shade. However, long-time exposure to blazing sunlight should be avoided in hot summer, when it needs to be shaded or cooled a little to prevent high temperatures from damaging it.
