Origin
The Oreocereus, also known as the Old Man Cactus, has its origin in the Andes region of South America. This type of cactus is indigenous to high-altitude areas of Argentina, Bolivia, Chile and Peru. The Oreocereus has adapted to the extreme weather conditions of the mountains, where temperatures can be both very high and extremely low.
Characteristics
The Oreocereus is easily recognisable by its distinctive tall, cylindrical shape and its white, woolly 'hair' that covers the spiky skin. This hair growth serves as a natural sunscreen, protects against strong winds and helps to reduce evaporation loss. Notably, the plant only develops this hair growth after a number of years. The cactus can reach a height of about 3 metres and blossoms with red or yellow flowers.
Care
The Oreocereus requires a specific care routine given its natural habitat in the mountains. The cactus thrives best in full sun and needs well-draining soil. Generally, the Oreocereus is a fairly tolerant plant and thrives well with a minimum of care. Fertilisation is not necessary and during the cold season it is important to reduce watering. Overwatering can lead to root rot, which can damage the plant.
