About Cereus spegazzinii
Cereus spegazzinii, also known as Spegazzini's Cherry Cactus, is a slow-growing, columnar cactus branching from the base, producing segmented, bluish-green stems with short spines. Its sculptural form and segmented stems make it ideal as an ornamental plant in desert gardens, rockeries, or as a potted specimen in bright indoor settings. It can produce nocturnal white flowers, although these are uncommon in cultivation.
Native range
Argentina, Bolivia, and Paraguay
Care tips
It requires full sun for optimal growth and potential flowering, although it tolerates light partial shade in very hot climates. Watering should be moderate during the growing season (spring-summer), allowing the substrate to dry out completely between waterings, and almost none in winter to prevent rot. Use a very well-draining substrate, specific for cacti and succulents, with a good proportion of sand and perlite. A common mistake to avoid is overwatering, which is the main cause of death for this species.
