Acanthorhipsalis monacantha is an epiphytic cactus of the Rhipsalis family with flattened or 3-angled waxy green stems that become pendant with age. Acanthorhipsalis monacantha has springtime flowers that are a bright, golden orange, unusual color for rhipsalis.

R. 'Mini' forms myriads of "knobby" green shapes with tufty brown spines.

This plant, as with all Rhipsalis, prefers filtered light and slightly more humidity than other cacti. Soil should be largely composed of organic material, such as peat or sphagnum moss. Water thoroughly when top of soil is dry to the touch. Prefers days that are 70 to 80 degrees Fahrenheit. Prefers nighttime temperatures no cooler than 50 degrees Fahrenheit, especially in winter. Protect from frost.
