Anthurium cutucuense

An epiphyte of Ecuadorian cloud forest

Anthurium cutucuense is endemic to Ecuador’s lower Andes, including the Cordillera de Cutucú. It climbs as an epiphyte in cool, persistently humid cloud forest, with records around 1,400 m and others from roughly 1,800–2,300 m. Mossy trunks, regular mist and filtered mountain light define its natural setting.

Care for Anthurium cutucuense

• Light: Give bright filtered light without direct midday sun or trapped heat. Keep the upper stem within the same cool, humid air as the root zone.
• Watering: Maintain even moisture in the pot and attached aerial roots. Water when the surface starts to dry and let excess leave the container immediately.
• Humidity and airflow: Aim for 75–90% relative humidity with constant gentle air exchange around the leaves and support.
• Temperature: Keep at 16–24 °C with cooler nights. Protect this cloud-forest climber from sustained temperatures above 26 °C.
• Substrate and repotting: Acclimate Anthurium cutucuense with the nursery root ball intact long enough to understand its moisture use and the condition of the climbing stem and attached roots; choose the later repotting moment from new roots and steady leaf expansion. Later, use a ventilated pot, fine bark, chopped sphagnum or coir and pumice, together with a slim moisture-holding support.
• Feeding: Feed at very low concentration during visible growth and flush with plain water every 3–4 weeks. Strong fertiliser can damage cool-growing roots.
• Cloud-forest support and propagation: Guide the epiphytic climbing stem onto a slim moisture-holding support and keep the bullate leaves out of warm stagnant air. Rinse the recessed surface gently, dry it with airflow and propagate from a rooted node section only after the plant is established.

Wilting, leaf spots and slow growth

• Droop and yellowing at the same time: A light container, dry support and shrivelled aerial roots indicate thirst; moisten the pot and attached root zones. Little change in pot weight or soft dark node with yellowing indicates root stress. Heat can also cause limp foliage while moisture remains adequate.
• Trimming confirmed failed roots: Healthy roots feel firm at the base and supported nodes. Remove hollow or slippery roots using a clean sharp cutting tool, use a ventilated fine airy mix and secure active roots to a slim moisture-holding support. Before cutting Anthurium cutucuense, photograph the root system and confirm failure by texture; preserve every firm section, sterilise the tool between cuts and keep the crown stable while new roots develop.
• Marginal browning and root moisture: Brown margins may begin with dry roots, salts or sustained heat. Check pot and support moisture separately, use low-mineral water and restore 16–24 °C with cooler nights and constant airflow.
• Reading the edge of a dark lesion: Dry fixed marks may begin with rubbing against a support. Wet, yellow-edged or enlarging lesions need isolation, dry foliage and daily photographs; dry recessed leaf surfaces promptly.
• Growth pauses after stress: A stalled tip or smaller leaves may begin with weak light, lost support contact or temperatures above 26 °C. Give bright filtered light, cooler nights and moving humid air around the full climbing stem.
• Inspecting nodes, veins and leaf backs: Thrips and mites hide in the deeply textured foliage, while mealybugs can settle at nodes. Isolate, clean hardened leaf recesses and the support, apply a product whose instructions cover that pest. Follow the labelled interval between applications and look for fresh feeding marks weekly until four clean checks have passed.
• Heat, wet grooves and dry roots: Recessed leaves and attached roots both suffer in hot stagnant air. Keep the stem on a slim moisture-holding support, rinse hardened grooves gently and dry them immediately with cool moving air.

Pet risk from Anthurium cutucuense

• Not pet-safe. This plant contains calcium oxalate crystals that can cause immediate pain and irritation if chewed.

The name Anthurium cutucuense

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Heinrich Wilhelm Schott established the genus in 1829 in Wiener Zeitschrift für Kunst, Litteratur, Theater und Mode, volume 3, page 828.

Cutucuense means “from Cutucú”, referring to Ecuador’s Cordillera del Cutucú. Michael T. Madison described Anthurium cutucuense in 1978 in Selbyana 2: 256.
