A pendent epiphytic shrub in the Ericaceae (blueberry family) from the Andean cloud forests, distinguished by its dense white woolly indumentum coating the stems and new growth. Like its relatives, it grows from a lignotuber and produces waxy, tubular hanging flowers adapted for hummingbird pollination. The most cold-demanding species in the genus, making it a specialist's plant. Best displayed where its pendant flowers and woolly texture can be appreciated; never remove spent peduncles. An advanced-care plant.

• Light: Bright filtered indirect light, equivalent to dappled forest canopy; avoid direct sun which scorches the foliage.

• Soil: Open, acidic epiphytic mix of orchid bark and perlite, or mounted on cork or tree fern with sphagnum; excellent drainage essential. Use rainwater or reverse osmosis water to avoid mineral buildup.

• Temperature/Humidity: The most cold-demanding Ceratostema — day temperatures of 60-68°F with a distinct nighttime drop to 46-54°F; sensitive above 77°F. Very high humidity of 80-90% is essential, with constant good airflow.

• Watering: Keep consistently moist but never soggy; water thoroughly when the top layer feels slightly dry, allowing excess to drain completely. Never let roots dry out fully.

• Fertilizer: Feed lightly with a low-pH ericaceous formula during active growth; sensitive to fertilizer salt buildup. Reduce in winter.
