Ceratostema Zamorana

First described in 2021 and named for the Zamora Chinchipe Province of southeastern Ecuador where it was discovered, Ceratostema zamorana is among the more recently introduced species in the genus to reach the collector trade — an endangered epiphytic shrub of considerable rarity due to its extremely limited geographic range in the Cordillera Real of the eastern Andes. Like all Ceratostema, it belongs to the Ericaceae family and produces the pendant, waxy, tubular flowers that have made the genus an object of obsession among collectors of unusual flowering epiphytes — dangling from arching, leathery-leaved stems with a sculptural elegance that photographs poorly and impresses enormously in person. Its conservation status reflects the particular vulnerability of cloud forest endemics with narrow ranges, making cultivated specimens from responsible nurseries genuinely important for the species' presence outside its threatened native habitat.

Compared to the cooler-adapted gualaquizensis group, C. zamorana is described as an intermediate to warm grower — a function of its somewhat lower-elevation habitat — with preferred daytime temperatures of 68-82°F and slightly cooler nights of 59-68°F, making it a more tractable species for growers who cannot maintain the very cool nighttime conditions required by higher-elevation Ceratostema. Provide bright indirect light replicating dappled forest canopy with excellent airflow at all times to prevent fungal issues in the high humidity the species requires. High humidity of 60-80%+ is essential. Keep the medium consistently moist but never waterlogged in a very open epiphytic substrate — cork bark mounting with sphagnum or a coarse bark and perlite mix with excellent drainage. Use rainwater or reverse osmosis water to prevent mineral accumulation on the delicate root system. Not known to be toxic to humans or pets.
