Tillandsia juncea

A widespread epiphytic Tillandsia from Mexico, Central America, the Caribbean and northern South America, forming dense clumps of stiff, narrow, rush-like grey-green leaves. It grows on trees in fairly open, seasonally dry to moist forest from near sea level to about 1800 m. Grow it mounted, in bright light with good airflow, watering it well and letting it dry within a few hours.

Where it grows wild

Epiphytic on trees and shrubs. Its narrow, scaly, rush-like leaves are typical of Tillandsia species from bright, seasonally dry forests and open woodland, where plants dry quickly after rain or mist. The literature consulted gives little habitat detail.

GBIF records run from 10 to 1782 m, with a median of 736 m (316 records), so most plants grow in the foothills and lower mountains.
