Brassia peruviana
Also known as: The Peru Brassia or Oncidium peruvianum in the subfamily: Epidendroideae
Native to: Peru
General Information
The Peru Brassia is a large cool to warm growing epiphytic orchid belonging to the sub family Epidendroideae native to Peru.
Plant Description
Grows to 44-65cm. Each new growth has a single lance shaped oblong shaped leaf that grows to 3-60cm long. Pseudobulbs grow to 4-5cm
Care Notes
These orchids have a fine root system that can quickly die back if left dry for too long, but also does not like to be kept wet, so water regularly but ensure that the mix is dry before watering.
Climate
Grows at low to high elevations. Rainfall ranges from 114mm to 632mm per day, heaviest in May and lightest in December. Humidity ranges from 76% to 81%, highest in July and lowest in February. Temperature ranges from 16C to 29C, highest in February (17C to 29C) and lowest in January (16C to 28C).
Watering
These orchids are sensitive to excessive watering and should only be watered when they look thirsty. Water infrequently and ensure that the roots are dry before watering. Keep an eye on them especially during hot weather as overwatering can lead to rot, whereas underwatering may result in wilting or shriveling, which while unattractive, will not kill the plant.
Potting
These plants are quite forgiving and will do well repotted ever 2-3 years. The mix should be coarse, well draining, and allow space for air to move and for roots to grow.
Alternatively, these plants will also do well mounted to tree fern or cork slabs, or mounted to trees.
Best time for repotting or mounting the orchids is the end of winter when new growths start to appear. Avoid repotting during hot weather,
