Utricularia heterochroma

A very small, possibly perennial rheophytic bladderwort of section Mirabiles, known only from a few tepuis and sandstone massifs in southern Venezuela. It grows among mosses on wet sandstone cliffs and rocks by waterfalls, under spray and in fast water, between about 1,100 and 2,450 m. Treat it as a cool, constantly wet highland plant; cultivation information is essentially absent.

Where it grows wild

Wet sandstone cliffs near waterfalls among mosses, water-saturated moss cushions on rock, the dripping bases of falls and rocks by cascades in stream shallows. The plant sits in a film of moving water and constant spray.

Wikipedia gives 1,760-2,450 m; 24 GBIF specimens with an elevation span 1,112-2,430 m, median about 2,000 m.
