Cattleya nobilior

Cattleya nobilior is found from Brazil to Bolivia at 500 to 700 meters (1.650 to 2,300 feet) in bright, airy positions on tree trunks or horizontal limbs of rough-barked trees, which grow at the very edge of the cliffs above the river valley. Water vapor from the river is carried aloft, thereby keeping humidity higher in the microclimate where Cattleya nobilior grows and providing some moisture, even during the long dry season. Blossoms are almost 5 in. (12 cm) across, the largest bifoliate Cattleya. Flowers open very flat with the segments fully expanded. They are very long-lasting with a faint but pleasant fragrance. Blooms in late winter or early spring. In cultivation, water should be reduced gradually in the autumn after new growths mature. Water once every 3-4 weeks with an occasional, early morning misting.
