Where it grows wild

A saxicolous plant: herbarium labels describe it on rock faces and cliff walls (one noted a south-east exposure) in the Sierras de Tandil, Sierras de Balcarce and Sierra La Peregrina in Argentina, and at sites such as Casa de Pedra and Rincão do Inferno in Rio Grande do Sul. It forms dense clumps of stiff, silvery-green rosettes.

Recorded at low elevations, about 75–400 m, in the Argentine sierras.
