Anthurium peltigerum

A western Andean epiphyte

Anthurium peltigerum ranges from south-western Colombia into Ecuador, including the Alto Tambo area of Esmeraldas. It grows epiphytically in wet tropical Andean forest; Colombian records place it at about 950–2,100 m. The habitat combines high humidity and regular rain with the airflow and quick drainage of roots attached to trees.

Care for Anthurium peltigerum

• Light: Place in medium to bright filtered light. Gentle early or late sun is suitable after acclimation, while hot midday sun can scorch the leaves.
• Watering: Water when the surface has dried but the centre of the pot is still slightly moist. Soak fully and allow free drainage around the epiphytic roots.
• Humidity and airflow: Maintain 60–80% relative humidity with light air circulation. Dry new leaves promptly and keep fresh air moving around them.
• Temperature: Keep at 20–28 °C and above 18 °C at night. Protect aerial roots and the pot from cold surfaces.
• Substrate and repotting: Use the nursery root ball as a stable baseline for Anthurium peltigerum while it acclimates; record how quickly the airy epiphytic root zone dries, then repot when fresh roots and a repeatable watering interval are visible. Later, use a close-fitting ventilated pot with bark, coco chips and pumice, adding a little coir for moisture retention.
• Feeding: Feed epiphytic roots with a weak complete fertiliser during growth. Water through with plain water every 4–6 weeks to clear salts from bark and root surfaces.
• Peltate leaf and epiphytic-root care: Keep the leaf attachment and lower surface dry after rinsing, and let aerial roots enter the open mix as the broad peltate blades gain weight. Propagate from rooted offsets or node-bearing stem sections.

Wilting, root problems and pests

• Yellow foliage with reduced firmness: Reduced pot weight, dry open mix and shrivelled aerial roots indicate thirst; water until the mix is evenly moist and let excess escape. A pot that stays weighty after watering, damp compacted mix and yellow limp leaves indicate poor root aeration; set watering aside while you inspect the roots.
• A compromised root ball: Root firmness matters more than the changing colour of the outer layer. Remove hollow or slippery roots with scissors disinfected before use, keep the stem above a coarse close-fitting mix and guide active aerial roots into the pot or support. Before cutting Anthurium peltigerum, 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.
• Brown margins with a moist root ball: Brown tips can point back to rapid drying or mineral-rich water. Restore a steadier watering interval while keeping both the pot and exposed roots aerated.
• New dark tissue on the leaf: Check nearby surfaces and direct light when one dry mark appears. Move the plant away from others if a damp mark spreads towards healthy tissue.
• No movement from the centre: When growth stalls, compare light with the temperature and activity of exposed roots. Use filtered light, 20–28 °C and warmer surfaces around aerial roots.
• Hidden pests on stems and foliage: Scan petiole bases for scale or mealybugs and distorted new growth for thrips. Isolate, remove visible pests, work the labelled treatment into every hiding place, schedule the next treatment exactly as directed on the label and watch the central growth point every seven days for four weeks.
• Water and pests at the leaf joint: Water and pests can hide around the point where the petiole joins the underside of the blade. Dry this area after cleaning and inspect it closely when the leaf develops speckling.

Pet warning for Anthurium peltigerum

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

The name Anthurium peltigerum

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.

Peltigerum combines Greek peltē, “shield”, and Latin -ger, “bearing”: “shield-bearing”. Luis Sodiro described Anthurium peltigerum in 1905 in Anales de la Universidad Central del Ecuador 19: 316.
