Cattleya rex is a species of epiphytic orchid of showy white flowers, native to montane forests in Peru and Bolivia.
Cattleya rex requires a temperate climate (16 °C at night and 28 °C during the day) and good ventilation (a dark and enclosed environment will attract fungi or bacterial diseases).
This species does not tolerate dryness for long periods, so watering must be done regularly and should be reduced in frequency during winter. However, the growing medium (cork slabs, baskets or pots) must have good drainage, so the roots can dry properly after watering or root rot may appear.
Cattleya rex is known from a few localities in the regions of San Martin and Puno in Peru and the department of La Paz in Bolivia. It occurs in montane forests and low montane seasonally dry forests at 800–2500 m, growing on tree branches.
