Harrisia pomanensis

A sprawling, slender-stemmed night-blooming cactus of the dry Chaco and Monte scrub of northern Argentina, southern Bolivia and western Paraguay. It wants hot, very bright summers with storms, and a cool, almost rainless winter rest; large white nocturnal flowers follow a proper dry winter.

Where it grows wild

Recorded at 250–1175 m (median 350 m), mostly lowland plains and foothills.
