Scientific name: Piper auritum Kunth.

Taxonomic synonym: Piper sanctum (Micah) Schlecht.; Piper auritum var. amplifolium C. DC.

Family: Piperaceae

Habitat: Native from Tropics and Mesoamerica (southern Mexico, Guatemala, Panama, northern Colombia), now extended from Mexico to Florida.

It grows spontaneously and permanently in moist woodlands, at altitudes up to 1,300 meters. Easily identifiable by their large aromatic leaves that can be up to more than 30 inches long.

Used to live in the canopy of the trees, the grass grows best with shade or partial shade. It does not tolerate frost, so in climates with winter season can lose the aerial part of the plant. It does not resist drought and must have permanently moist soil.

However, in tropical climates where the temperature and weather conditions are favorable, it can be an invasive plant, as it has become in Hawaii, due to growth in rhizomes able to form large colonies.
