Anthurium plowmanii

A bird’s-nest Anthurium shaped by seasonal dryness

Anthurium plowmanii ranges from northern Peru and Bolivia through western Brazil to Paraguay. Unlike many collector Anthuriums, it grows in seasonally dry tropical forest as an epiphyte or lithophyte, with records from about 50–900 m and also from Amazonian várzea and terra-firme habitats. Its rosette persists through pronounced dry periods and often occupies exposed rocks or trees.

Growing Anthurium indoors

• Substrate and repotting: Wait until Anthurium plowmanii has active outer roots before disturbing the broad rosette, unless the nursery mix has lost its open structure. Use a stable close-fitting pot with coarse bark, coco chips, pumice and a modest amount of coir.
• Light: Give medium to bright filtered light, including gentle early or late sun after acclimation. Keep the rosette away from hot midday glass.
• Humidity and airflow: A range of moderate to high humidity suits this robust rosette when air circulates between the leaves.
• Feeding: Use a dilute complete fertiliser while leaves and roots are growing. If Anthurium plowmanii keeps producing roots or leaves under lower light, continue feeding lightly; reduce or pause when growth stops, and rinse the mix with plain water occasionally.
• Ruffled rosette and propagation: Clear debris and water from the ruffled central rosette and give the spreading leaves generous space. Separate only basal offsets that already carry their own roots.

Pest and health checks for Anthurium plowmanii

• Sorting thirst from root stress: Check below the dry upper 3–4 cm before watering. A pot that lifts easily with dry deeper mix and folding ruffled leaves needs a full soak; yellow limp leaves above a persistently heavy pot call for a root inspection.
• Firm tissue during root recovery: Firm roots should sit below a crown that remains dry and visible. Remove soft or hollow roots with disinfected scissors, return the plant to a stable coarse mix and preserve the upper-layer drying interval.
• Pest checks around active growth: Thrips shelter in the emerging folds; mealybugs and scale can sit beyond view in the deep ruffled centre. Isolate, clear visible insects with a damp swab and apply a labelled treatment to accessible leaf bases. Follow the label interval and inspect the centre every week for a month.
• Tip damage after irregular watering: Brown tips can come from an overlong dry period or fertiliser salts. Check deeper moisture, water thoroughly when due and flush the root ball; let the upper mix dry again afterwards.
• Spot movement and leaf-surface moisture: Dry bleached areas point to sun, while soft marks at leaf bases can come from trapped crown water. Isolate spreading or yellow-edged lesions, keep the crown dry and mark the edge and check if it expands.

Anthurium plowmanii is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Anthurium plowmanii: where the name comes from

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Plowmanii honours the American ethnobotanist Timothy Plowman.

Heinrich Wilhelm Schott established the genus Anthurium in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 828.

Thomas Bernard Croat first described Anthurium plowmanii in 1987 in Candollea, volume 42, page 811.
