Origin
The Espostoa (Vatricania) guentheri, also known as the Peruvian Old Man Cactus, originally hails from the dry highlands of Peru. This species of cactus mainly grows at high altitudes and is adept at surviving in extreme climates. The plant has undergone a long and interesting evolution to adapt to its natural desert environment.

Characteristics
The plant is distinguished by its cylindrical shape and long, white 'hairs' that protect the cactus from the powerful sun. The Espostoa guentheri can grow to a height of 4 to 5 metres and tends to branch out over time. This cactus is a night bloomer, which means that its flowers open in the evening hours and emit a pleasant scent. The plant is densely covered with spines, which also serve as a natural deterrent against predators.

Care
As for the care of the Espostoa guentheri, it is important to note that this plant requires little maintenance. The plant prefers full sun or light shade and requires well-draining soil to grow in. It is recommended to water moderately and especially to ensure that the plant is not in standing water. This is to prevent root rot, one of the greatest threats to this type of cactus. In the winter months, it is essential to reduce watering and protect the plant from frost as the Espostoa guentheri is not frost-hardy.
