The Christmas Orchid
Cattleya trianae is a large, evergreen epiphytic orchid, prized for its big, fragrant blooms carried atop upright, club-shaped pseudobulbs. It holds the distinction of being the most awarded orchid species on record, and it serves as the national flower of Colombia.

A Colombian Native
This species comes from Colombia, where it grows as an epiphyte. Its long horticultural pedigree and sheer number of awards have made it something of a benchmark among cattleyas, and its cultural weight is reflected in its status as Colombia's national flower.

Light, Water, Rest
Grow this orchid in an open, coarse bark-based mix with perlite and coconut chips added, and give it bright light while shading it from hot midday sun. Aim for a winter minimum of 15°C and a summer ceiling near 28°C, watering and feeding regularly through the growing season while making sure water always drains freely away. Provide humidity through regular misting, then ease off on both water and feed over winter, keeping the plant bright and sunny. Like many orchids, it flowers best when the roots are a little snug in their pot.

Dividing Established Clumps
Propagation is by division, undertaken once a mature plant has outgrown its container. Each division needs at least three older pseudobulbs, carrying enough stored energy and water to support new growth and settle in after the disturbance of repotting.

Pseudobulbs and Grand Flowers
Each upright, club-shaped pseudobulb rises from a short creeping rhizome and carries a single firm, leathery leaf up to 30cm long. Flowering stems emerge from the young mature growth in winter and early spring, their buds wrapped in thin pale green sheaths before opening into fragrant flowers up to 20cm across. Colour in the species ranges widely, from pure white through pale pink and lilac to dark magenta, typically with a darker lip and a yellow throat; named forms narrow that range, such as the pure white, yellow-centred 'Queen Elizabeth'.

Watch for Sap Feeders
Glasshouse red spider mite, scale insects, and mealybugs are the pests most likely to trouble this orchid. Thrips are a separate concern, as they tend to mark the flowers rather than the foliage.

Rot from Stale Air
This orchid is generally free of disease, but poor air movement can invite bacterial or fungal rot. Keeping tools clean and hygiene good also helps prevent virus diseases from spreading between plants.

Repotting on Its Own Terms
No pruning is needed for this species. Repot only when the plant has outgrown its container or the mix begins to break down, roughly every two to three years, and time the disturbance to when new growth appears in spring.
