About Broad-Sepal Gongora

Gongora latisepala · also called Broad-Sepal Gongora · tropical

Gongora latisepala is a distinctive epiphytic orchid characterised by unusually broad sepals relative to other Gongora species, giving its pendant flower racemes a bold, architectural appearance. Native to tropical South America, it shares the genus preference for basket culture, high humidity, bright filtered light, and an annual cool-dry rest to stimulate blooming.

Preferred mix: Open epiphytic bark mix in a hanging basket

Watch for — Yellowing lower leaves: Natural sequential leaf drop on old pseudobulbs is normal and not harmful. If new growth also yellows, check for overwatering, poor drainage, or root rot. Ensure the bark mix has not broken down into a water-retentive mush that suffocates roots.
