Guzmania blassii

Guzmania blassii Rauh is a tank bromeliad endemic to Costa Rica, known from about 36 herbarium and field records. It grows as an epiphyte on trees at forest edges in premontane wet forest, mostly at 700–1,500 m. Little is published about it beyond the original description, so this profile uses the herbarium record data and typical premontane Guzmania care.

Where it grows wild

An epiphyte on trees in wet forest and at forest edges (one label reads 'on a tree at the forest edge'). Records come from the Talamanca range, Fila Costeña and the central volcanic ranges.

Mostly 700–1,500 m; a single 3,450 m record is probably an error.
