Synonyms: Brassavola venosa, Bletia tuberculata.

Appearance
 
 
Size: Medium-sized orchid with spindle-shaped pseudobulbs measuring 10 to 20 cm long.
 
 
Leaves: Single leaf per pseudobulb, leathery, cylindrical or club-shaped, light green to dark green, measuring 15 to 30 cm long. Leaves are often slightly grooved or tubercular, hence the name tuberculata.

Flowers
 
 
Shape: Solitary, star-shaped flowers with narrow petals and sepals and a spoon-shaped white lip.
 
 
Color: Creamy white to pale green, sometimes with purple or green streaks or spots. The lip is usually white with a touch of green or purple at the base.

Blooming period: Several times a year, especially in summer and autumn, but can bloom at any time if conditions are favorable.

Cultivation
Climate and Environment
 
 
Temperature:Day: 22-30°C (tolerates heat well).
Night: 15-20°C (a day/night drop of 5-10°C promotes blooming).
Winter: Do not expose to temperatures below 10°C.
 
 
Humidity: 50-70%, ideal for mimicking its humid tropical habitat.
 
 
Light: Bright light to partial shade (2,000-4,000 lux). Can tolerate some direct morning or late afternoon sun, but avoid burning midday sunlight.

Watering
 
 
Growth period: Regular watering, allowing the substrate to dry out slightly between waterings. Pseudobulbs should remain slightly plump.
 
 
Winter rest: Reduce watering slightly in winter, but without letting the plant dry out completely.

Substrate
 
 
Type: Highly airy and draining mix for epiphytic orchids:Coarse pine bark (50%)
Charcoal (20%)
Sphagnum moss or coconut fiber (20%)
Perlite or clay pebbles (10%) to improve drainage.
 
 
Repotting: Every 2-3 years, or when the substrate degrades.
