Guzmania berteroniana

A Caribbean Guzmania best known from the montane rain and cloud forests of Puerto Rico (El Yunque, Toro Negro, Maricao), with further records from Hispaniola. It forms a tank rosette of green leaves with a bright red bracted spike. It wants cooler nights and wetter, more constantly humid air than lowland Guzmanias.

Where it grows wild

An epiphyte, sometimes on rocks or banks, in wet montane forest where cloud and frequent rain keep the air humid. Most observations come from the El Yunque rain forest and the Cordillera Central forests of Puerto Rico.

GBIF records with an elevation mostly fall between about 700 and 1,200 m, with a few higher, so it is a montane plant rather than a lowland one.
