Alcantarea extensa

A large rosette bromeliad of the granite inselbergs of Espírito Santo and neighbouring Minas Gerais and Rio de Janeiro, Brazil. Like other Alcantarea it grows on bare rock faces in full sun and holds water in its leaf bases. It wants strong light, a gritty medium and a warm climate with a cooler, drier winter.

Recorded from near sea level to about 1,660 m, with a median around 850 m.
