Tillandsia aeranthos

A hardy air plant from southern Brazil, Uruguay, Paraguay and northeast Argentina that forms clumps of stiff, silvery-green rosettes and bears pink bracts with deep blue-violet flowers. It is subtropical to warm-temperate: summers are warm, but winters are cool with occasional light frost. That makes it one of the easiest Tillandsia to grow in bright light and good air.

Where it grows wild

An epiphyte on trees and shrubs, and sometimes on rocks and cliffs, in humid lowland woodland, riverside forest and open country from the Atlantic coast inland to the humid Chaco. It takes water and nutrients through its leaf scales; the roots only anchor it.

The Spanish Wikipedia gives sea level to about 300 m. GBIF has almost no elevations for it; the single record at 2,529 m is probably an error.
