Anthurium pedatum

An epiphyte of Colombia’s Andean and Pacific forests

Anthurium pedatum is endemic to Colombia, with records from Cauca, Nariño and Valle del Cauca. It grows as an epiphyte in wet forest from roughly 350 to 2,100 m, spanning warm lower slopes and cooler cloud-influenced elevations. Its roots occupy trees and accumulated organic material beneath humid forest cover.

Care for Anthurium pedatum

• Light: Set in bright diffuse light, away from hot midday sun. Broad leaves benefit from even illumination and a cool position behind glass.
• Watering: Maintain light, even moisture and water when the surface starts to dry. Empty the outer pot after each thorough watering.
• Humidity and airflow: Aim for 65–80% relative humidity with steady air circulation around the leaf bases and emerging growth.
• Temperature: Keep at 18–26 °C with nights near 18–20 °C. Extended hot nights can reduce leaf size and vigour.
• Substrate and repotting: Let Anthurium pedatum settle in the original container first, using pot weight, root activity and clean new growth through the airy epiphytic root zone to decide when a later repot will cause the least disruption. Later, choose a stable pot 2–3 cm wider and an airy blend of bark, coir and mineral drainage.
• Feeding: Use a weak complete fertiliser during active growth and a lower dose whenever growth slows. Flush the pot with plain water every 3–4 weeks.
• Divided montane foliage and propagation: Allow the divided blades room to open and use a stable pot for the long petioles. Clean each lobe with a damp cloth and propagate from rooted offsets or node-bearing stem sections.

Root stress, leaf damage and slow growth

• A thirsty wilt or wet-root wilt: A noticeably lighter container and dry root zone point to thirst; wet the full root zone, then empty the saucer or cover pot. A container that still feels heavy, damp surface and soft yellowing point to root stress, especially after cool wet conditions; let the next watering wait while you check the deeper roots.
• Testing roots by texture: Firm roots with active tips can stay in place. Remove soft or hollow tissue using scissors sterilised before the cut, keep any short base at the surface and use a stable snug pot with an air-rich mineral mix. Before cutting Anthurium pedatum, 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.
• A newly browned tip: Brown margins may trace back to dry roots or accumulated salts, while warm stagnant nights can also damage montane foliage. Check the root ball first and flush salts with low-mineral water and restore air exchange around the leaves.
• A dark mark that needs daily comparison: Dry scorch keeps a stable edge after the light source is moved. A yellow-bordered lesion becomes urgent as soon as the outline moves; keep foliage dry, photograph the edge and seek advice if it keeps spreading.
• Stalled roots and foliage: When growth stops, compare current light with root activity and night heat. Hold the root zone near 18–20 °C at night and below 26 °C by day; during warm periods, improve airflow and let root moisture guide watering.
• Thrips scars and mite stippling: Raised brown bumps along the veins or petiole suggest scale; inspect petiole bases and lower leaf surfaces closely. Isolate, remove visible pests, apply a product labelled for the pest, follow the repeat timing printed on the label and check the same hiding places weekly until four clean checks have passed.
• Torn new lobes: Developing lobes need open space and cooler air while they harden. Stabilise the pot for the long petioles and clean each mature section separately.

Anthurium pedatum and pet safety

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

The name Anthurium pedatum

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.

Pedatum is Latin for “foot-like”, referring to the arrangement of the leaf divisions. Carl Sigismund Kunth first published it as Pothos pedatus in 1816 in Nova Genera et Species Plantarum 1: 78; the combination Anthurium pedatum appeared in 1841 in Endlicher and others’ Enumeratio Plantarum quas in Novae Hollandiae: 79.
