About Rattail cactus
Aporocactus flagelliformis, commonly known as the Rat Tail Cactus, is an epiphytic cactus species characterized by its long, slender, trailing, bright green stems. Its stems can reach up to 90 cm in length and are covered in small spines. In spring, it produces beautiful deep pink or red tubular flowers that bloom along the stems. It is ideal for hanging baskets or tall pots where its cascading stems can be showcased.
Native range
Mexico
Care tips
It prefers bright, indirect light; intense direct sunlight can scorch its stems. Water thoroughly when the substrate is dry to the touch, but avoid waterlogging, especially in winter. Use a well-draining substrate, specifically for cacti, or an orchid mix that mimics its epiphytic environment. A common mistake is overwatering, which can lead to root rot.
