Tillandsia gilliesii

A small, tough, grey Tillandsia of the dry country of western and central Argentina, also reaching Bolivia and southern Peru. Most records come from the Monte and pre-Andean regions of Mendoza, La Pampa, San Juan, La Rioja, Catamarca and Jujuy, where it grows on rocks, shrubs and trees in strong sun. It takes cold, dry winters with frost and hot summers, so it needs very bright light, excellent airflow and a dry, cool winter.

Where it grows wild

Arid and semi-arid scrub, dry woodland and rocky hills of the Argentine Monte, the Andean foothills and outlying sierras (including the Tornquist/Sierra de la Ventana area of Buenos Aires province), growing on rocks, shrubs and small trees. No species-specific habitat account was found; this is inferred from where the records fall.

Records range from the lowland Monte of La Pampa and Río Negro to Andean valleys in Jujuy and Bolivia; no elevation range was found.
