Where it grows wild

An epiphyte on trees in wet premontane and lower montane forest, including forest along rivers, for example at Las Cruces Biological Station near San Vito. Like other Guzmania, it catches rain and leaf litter in a tank formed by its overlapping leaf bases.

GBIF records span about 250–1555 m, mostly 800–1300 m.
