General Information
An epiphytic orchid native to South America (Brazil, Peru, Antilles) of considerable size, with large, fragrant flowers. The pseudobulbs form dense clusters, from which leaves up to 40-50 cm long and 4-5 cm wide emerge; in summer they produce long spikes that bear several very fragrant, sometimes excessively so, flowers; the sepals and petals are greenish-white or creamy-green, with numerous dark spots; the sepals are very long and their particular appearance has earned these flowers the name "spider orchid".
Light
Exposure to full light encourages flowering, so the plant can be placed in south-facing locations and can receive direct light, especially in spring, autumn, and winter. In summer, intense sunlight can burn the leaves, so it is advisable to shade the plant.
Temperatures
Ideal temperatures range between 18°C and 25°C; during the autumn and winter season, it should be placed in a heated room, but away from heat sources. The minimum winter temperature should never drop below 10°C, while in summer it can withstand temperatures above 30°C, provided the growing environment is adequately humidified and ventilated.
Watering
Watering should be abundant during spring and summer. Water should be supplied regularly, preferably in the morning; Brassia roots do not like to dry out, so watering should be quite frequent. Preferably use non-calcareous and slightly lukewarm water and remember to increase ambient humidity with frequent misting.
During the colder months, watering should be reduced to allow the pseudobulbs to enter a slight dormancy, and the roots should be kept slightly moist through misting.
Fertilization
Fertilization should be abundant, about every 15 days, only during the vegetative phase (usually between May and September), while during the dormant period it should be suspended (October-April). Fertilizer, in minimal doses, can also be misted onto leaves and aerial roots.
Propagation
Once mature, the plant produces numerous shoots from each pseudobulb, rapidly increasing in size. Division of the pseudobulb clumps (about 4-6 per cluster) should only occur when they are well developed and preferably in spring or early autumn.
Substrate
Finely or coarsely shredded non-resinous bark, possibly with the addition of fern fibers and sphagnum moss.
Flowering Season
Generally from late spring to summer.
