Alcantarea heloisae

A rock-dwelling bromeliad from the granite and gneiss outcrops of northern Rio de Janeiro state. Like other Alcantarea it grows on exposed rock faces in strong sun, with warm humid summers and a drier winter, and is grown much like a sun-hardy tank bromeliad.

Where it grows wild

Alcantarea typically root into cracks and thin mats of vegetation on bare inselberg slopes, catching water in their leaf rosette. This follows the genus; species-level habitat notes are scarce.
