Introducing the Oeoniella polystachys - Madagascar's Tropical Marvel

Discover the allure of the Oeoniella polystachys, an exquisite orchid species thriving in the vibrant ecosystems of eastern and northwestern Madagascar. Native to the hot lowlands and the Sambirano Valley, this resilient beauty is a testament to nature's captivating artistry. A strong-growing epiphyte, the Oeoniella polystachys elegantly adorns tree trunks and branches, creating a picturesque display in its natural habitat.

Cultivation Tips:

Light: Oeoniella polystachys flourishes in light levels ranging from 25000 to 35000 lux. Ideal conditions include moderately bright, dappled or diffused light, with a preference for full, direct, midday sun. Adequate air movement is essential for optimal growth.

Temperature: Embrace the warmth for thriving blooms! Summer days at an average of 30°C and nights at 23°C provide the perfect setting. While the orchid adapts well to intermediate conditions, it thrives even more under warmer temperatures.

Humidity: Create a humid haven with near 85% humidity for most of the year, dropping to approximately 80% during a brief 2-3 month period in spring.

Substrate, Growing Media, and Repotting: Oeoniella polystachys finds its home on 10 x 30 cm slabs, mounted with a small moss pad at the base. Mounted plants crave high humidity and daily watering, potentially increasing during hot, dry spells. Alternatively, a well-drained 10-15 cm pot filled with a fast-draining medium is an excellent option. Consider using medium-to-coarse fir bark or shredded tree-fern fiber mixed with chunky perlite and charcoal for optimal moisture retention and aeration. Repotting is advised when the medium shows signs of breaking down, ideally coinciding with new root growth.

Watering: Mimic the natural habitat with heavy watering during active growth, ensuring that conditions around the roots remain fresh and never stagnant or soggy.

Fertilizer: Nourish your Oeoniella polystachys with a balanced fertilizer at 1/4–1/2 the recommended strength, applied weekly during active growth. Transition to a high-nitrogen formula from spring to midsummer, shifting to a high-phosphate blend in late summer and autumn for optimal results.

Rest Period: Maintain consistent growing conditions throughout the year. During the dark, short-day conditions of temperate latitude winters, reduce watering and fertilizer, ensuring the plant never dries out completely.

This is a blooming size in a 3" pot, about 1 to 2 years to bloom, grown from seed, limited!
