Aporocactus martianus

A trailing rat-tail cactus from the cloud and oak forests of Oaxaca, where its long, thin stems hang from trees and rocks at around 1,500-2,300 m. It wants bright but not baking light, cool nights and a dry, cool winter rest. Treat it as a hanging-basket cactus kept in a montane, not desert, climate.

Where it grows wild

Grows on trees and mossy rocks in montane cloud forest and oak forest, with stems creeping or hanging and sometimes making aerial roots. Locally abundant within a small range.

Mostly 1,500-2,300 m; the measured median is 2,250 m. A few low records (38-149 m) are probably misplaced or cultivated.
