climbing cactus

The term "climbing cactus" refers to certain species within the cactus family (Cactaceae) that have adapted to grow upwards, often by clinging to other plants or surfaces. These cacti are typically found in tropical and subtropical regions of the Americas.

Unlike many ground-dwelling cacti, climbing species often have thin, flattened stems that help them absorb water and adhere to their supports. Some examples include species from the genera Epiphyllum and Rhipsalis. These plants may use spines or aerial roots to help them climb. While most cacti have leaves reduced to spines to minimize water loss, climbing varieties may have more developed stems that are adapted for photosynthesis. Some climbing cacti are also known for their large, fragrant, night-blooming flowers.123
