Disocactus flagelliformis Rat Tail Cactus

Rat Tail cactus is the common name for Disocactus flagelliformis (or Aporocactus flagelliformis) and is native to Mexico. This slender, attractive, outdoor succulent is an epiphytic plant. This means it can grow naturally in low soil cracks such as tree crotches and rocky crevasses.
Its thick stems grow tall before the weight of the stems cause it to bend and either hang out of its pot, or trail along the ground. This tall, trailing cactus is one of the most widely cultivated cacti in its genus. Rat Tail cactus can grow up to 6 feet in length.
Bristly “hair” covers the limp stems which can be trained into many shapes and forms. The flexible, branching, stems about a half inch in diameter.
