Guzmania wittmackii

Guzmania wittmackii is a large bromeliad, about 80 cm tall in flower, from the wet premontane and cloud forests of the western Andes of southern Colombia and Ecuador. Its tall inflorescence carries red to pink or magenta bracts and white flowers, and it is a parent of many commercial Guzmania hybrids. It wants warm-to-intermediate, humid, bright-shaded conditions with water in its central cup.

Where it grows wild

Specimen labels describe it as an epiphyte on trees in wet premontane forest, cloud forest and riparian secondary forest, often at forest edges and even on trees at pasture margins. Well-known sites include the Mindo cloud forest and Reserva Maquipucuna in Pichincha, Ecuador, and Reserva Natural La Planada in NariΓ±o, Colombia.

Herbarium specimens range from 50 to 3325 m, but most are at 850–1450 m, median about 1120 m (64 specimens with elevation). A Colombian source gives 1050–1830 m.
