Guzmania poortmanii

A bromeliad endemic to Ecuador, growing in moist montane forest and listed as threatened by habitat loss. The only georeferenced records come from about 2760 m, high in the Andean cloud forest, so it should be grown much cooler than the lowland Guzmania hybrids of the houseplant trade. Almost nothing species-specific is published on its ecology or cultivation.

Where it grows wild

Subtropical or tropical moist montane forest in the Ecuadorian Andes. Like most Guzmania it is probably an epiphyte on mossy trunks and branches in cloud forest, holding water in its central rosette, but its exact habit is not recorded in the sources checked.

The two georeferenced GBIF records are at about 2760 m, in upper montane cloud forest.
