Anthurium clavigerum

Natural range and habitat of Anthurium clavigerum

Anthurium clavigerum is native across Central and tropical South America and grows as an epiphytic subshrub in wet tropical forest.

The stem climbs along trunks and other firm surfaces, attaching through aerial roots. Its transition from simpler juvenile foliage to deeply divided adult leaves is part of this climbing development.

Caring for Anthurium clavigerum

• Keep the active stem well lit: Bright filtered light around the active nodes helps keep the gaps between successive leaves shorter. Reposition the plant if the upper foliage is well lit but the growing stem remains shaded.
• Temperature and humidity: Keep it around 18–29 °C. Protect it from prolonged temperatures below 15 °C. A humid 60–80% range works well when air can move gently around the leaves.
• Check the pot and attached roots separately: Water the root ball when its upper layer begins to dry. Moisten rooted sections of the support only when they also need water.
• Feeding: Feed lightly while the climbing stem is extending and new roots are active. Reduce feeding as growth slows.
• Install a strong support early: Use a rigid plank, trunk or wide moss pole and anchor it securely. Tie the flexible stem loosely while guiding active aerial roots towards the surface.
• Potting mix and stability: Use a coarse mix and a heavy container that can balance the support and widening foliage.
• Repotting: Give the roots more room when they crowd the container; also repot if the plant and its support become unstable. Choose a pot just a little larger and secure the support again as you repot.
• Propagate from a healthy node: Choose a section with an active node and an aerial root or visible root bud. Keep it warm and lightly moist until new roots establish.

Problems and solutions for Anthurium clavigerum

• Later leaves stay small or lightly divided: Young climbing growth may still be juvenile. If the stem has only recently begun to climb, keep it attached and judge the next leaves as more nodes establish. On an established stem, move the active section into brighter filtered light and secure each new node against the support so its aerial roots can attach.
• Long bare gaps develop along the stem: Increase filtered light around the active section and secure fresh nodes against the support. A rooted top section can be propagated if older lower growth remains bare.
• The support shifts or the root ball lifts: Re-anchor the structure in a heavier container before another large leaf opens. Stabilise the base before tightening or changing stem ties.
• Leaf sections tear or crease: The broad blade has met a wall, doorway or neighbouring plant. Clear a wider path for the next leaf; the existing damage will remain visible.

Anthurium clavigerum 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.

What does Anthurium clavigerum mean, and who first published it?

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Clavigerum means “club-bearing”, from Latin clava, “club”, and -ger, “bearing”.

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

Eduard Friedrich Poeppig first described Anthurium clavigerum in 1845 in Nova Genera et Species Plantarum, volume 3, page 84.
