Habitat
Ceratostema zamorana is endemic to southern Ecuador, particularly the Zamora-Chinchipe region, where it inhabits cloud forests of the eastern Andes. It grows at elevations between 1,600 and 2,400 metres, often as an epiphyte or hemiepiphyte on mossy branches, occasionally rooting terrestrially in deep organic soils. Its habitat is characterised by high rainfall, persistent mist, and cool, stable temperatures.
Description
This species is an evergreen shrub or small climber in the Ericaceae. Plants can reach 1–3 metres in height when supported by surrounding vegetation. The leaves are narrowly elliptic to lanceolate, coriaceous, and glossy, typically 5–12 cm long, with entire margins. The flowers are pendent, tubular to campanulate, measuring 2.5–3.5 cm in length, and are most often bright pink with dark purple to yellow tips, adapted to hummingbird pollination. The fruit is a berry, globose, purplish to black when mature, containing numerous small seeds dispersed by birds.
Cultivation
Ceratostema zamorana requires bright, diffused light with protection from direct midday sun. It grows best in a moist, humus-rich, acidic substrate (pH 4.5–5.5), resembling the organic layers of montane forests. Watering should be frequent to maintain even moisture, but the plant must never sit in stagnant water. High humidity (70–90%) is essential, along with good air circulation. The species thrives at daytime temperatures of 18–24 °C and nighttime temperatures of 10–14 °C, reflecting its native montane conditions. Regular feeding with a dilute acidic fertiliser supports flowering and foliage growth. Due to its sensitivity to drought and alkaline conditions, it is recommended for cultivation under glass or in specialised highland conditions.
