General information
A large, epiphytic orchid native to South America (Brazil, Peru, and the Antilles), it produces large, fragrant flowers. The pseudobulbs form dense clusters, from which emerge leaves up to 40-50 cm long and 4-5 cm wide. In summer, they produce long spikes bearing several very fragrant, sometimes excessively fragrant, flowers. The sepals and petals are greenish-white or creamy-green, with numerous dark dots. The sepals are very long, and their distinctive appearance has earned these flowers the name spider orchid.
Light
Full sunlight encourages flowering, so the plant can be placed in south-facing locations and receive direct sunlight, especially in spring, autumn, and winter. In summer, intense sunlight can burn the leaves, so shading is recommended.
Temperature
Ideal temperatures are between 18° and 25°C; during the autumn and winter seasons, it should be placed in a heated room, but away from heat sources. The minimum winter temperature should never fall below 10°C, while in summer it can tolerate temperatures above 30°C as long as the growing environment is adequately humidified and ventilated.
Watering
Water abundantly during the spring and summer months. Water regularly, preferably in the morning; Brassia roots don't like to remain dry, so watering should be fairly frequent. Use non-calcareous, slightly warm water, and remember to increase humidity with frequent misting.
During the colder months, watering should be reduced to allow the pseudobulbs to enter a slight rest period, and the roots should be kept slightly moist by spraying.
Fertilizations
Fertilizer should be applied generously, approximately every 15 days, only during the growing season (usually between May and September), while it should be suspended during the dormant period (October-April). Fertilizer, in minimal doses, can also be sprayed on leaves and aerial roots.
Multiplication
Once mature, the plant produces numerous shoots from each pseudobulb, rapidly increasing in size. Dividing the pseudobulb clumps (about 4-6 per bunch) should only occur when they are well developed, preferably in spring or early autumn.
Substrate
Non-resinous bark, roughly chopped, possibly with the addition of fern and sphagnum fibres.
Flowering season
Generally from late spring to summer.
