Did you know
- The genus name Cleistocactus comes from the Greek 'kleistos' meaning closed, because the tubular flowers never fully open.
- Silver torch cactus is covered in dense white hair-like spines that protect it from intense UV radiation at high altitudes.
- In its native Bolivia, this cactus grows at elevations above 9,000 feet in the Andes mountains.
- The dark red tubular flowers are pollinated by hummingbirds that can access nectar through the narrow opening.
- A silver torch cactus must typically be at least 10 to 15 years old before it produces its first flowers.
