Cattleya cinnabarina

Cattleya cinnabarina, formerly Laelia cinnabarina, is a rock-dwelling orchid from the highlands of southeastern Brazil. Its tall, slender pseudobulbs each carry a single leaf and an upright spike of about a dozen bright orange flowers. It grows on exposed rock in strong light, with a marked cool, dry winter, and it does best when grown hard: bright, airy and dry between waterings.

Where it grows wild

It is a lithophyte, one of the rupicolous laelias, growing on rock outcrops in the highlands of Minas Gerais and Rio de Janeiro. Plants sit in cracks and on rock faces, often among grasses and small shrubs, exposed to strong sun and wind, with roots that dry quickly after rain.

Reported at 800–1500 m. The GBIF records span 868–1781 m with a median of 1310 m.
