Alocasia portei

A giant Philippine Alocasia with a thick trunk and huge, deeply lobed, leathery leaves that can exceed 1.5 m. It is endemic to Luzon (Laguna, Quezon, Camarines Sur), where it grows in secondary forest from near sea level to about 600 m. It is easy but enormous in cultivation: think greenhouse, conservatory or tropical garden, not windowsill.

Where it grows wild

Terrestrial in secondary forest and forest edges at low to middle elevations. It is anecdotally common and widespread, but botanical collections are few. Its size and habit point to open, disturbed forest with more light than the small jewel Alocasias get.

Recorded from 0–600 m. The single measured site near Los Baños, Laguna is lowland, which matches the hot measured days.
