Brassia Orchid Description
The 35 spectacular, fee-blooming species of Spider Orchids mimic the look of spiders to attract their spider-hunting wasp pollinators. They are found in wet forests from sea level to 5.000 ft. in the tropical Americas. The yellowy green flowers are often fragrant. They appear from the base of the large pseudobulb and are usually beautifully spaced on long inflorescences that last 6 weeks or more. Most bloom generously on gracefully held, well-spaced flowering sprays in late spring or summer, but twice-a-year bloom is common. They are often interbred within the Oncidium Alliance, their presence in a pedigree signaled byt eh spidery or pointy look of the blooms. The genus was named for 18th-century botanical artist William Brass.
How to Grow
All brassia orchids are easy to grow and flower in medium light on any windowsill except northern ones (give them slightly less light than Cattleya), and in greenhouses under medium light, in intermediate to warm temperatures (55-65ºF winter nights). Grow them in baskets or pots; the roots will often climb out of the mix, wich is normal. Add humidity with misting and humidity trays. Fertilize regularly while a they are growing, wich helps encourage twice-a-year bloom. Give plants a decided 2-4 week rest with higher light after growth is complete. brassia orchid don’t like to be repotted often.
