Heptapleurum arboricola 'Charlotte'

Where the species behind Heptapleurum arboricola 'Charlotte' grows naturally

Heptapleurum arboricola is native to Taiwan and Hainan. In the wild it grows in warm, humid forest, including stream-side habitats beneath the forest canopy, and can also grow on trees.

How to care for Heptapleurum arboricola 'Charlotte'

Keep ‘Charlotte’ in bright indirect light. The cream leaf areas need good light but can scorch after a sudden move into strong direct sun. Increase sun exposure gradually when moving it closer to a sunny window.

Keep temperatures around 18–24 °C and avoid prolonged temperatures below 10 °C. Aim for 50–60% humidity with warm, steady conditions. Avoid very dry heated spots; there is no need to keep the leaves wet.

Use a loose houseplant mix that drains well and holds some moisture between waterings.

Let the mix dry somewhat between waterings, but water again before most of it dries out. Check deeper in the pot as well as at the surface: the pot should feel clearly lighter, with the mix around the roots no longer wet but still retaining some moisture. This takes longer in darker or cooler conditions.

A light feed while the plant is actively growing is enough.

Repot when the roots are crowded. If water no longer moves through the mix properly, check the drainage holes and root ball. Replace deteriorated mix; increase pot size only when the roots need more room.

If one branch repeatedly produces only green leaves, cut it back to the last clearly variegated growth.

Common problems with ‘Charlotte’

• New leaves are becoming much greener: Move the plant gradually into brighter indirect light and watch the next few leaves. One greener leaf is not proof of permanent reversion. If the same shoot repeatedly produces fully green leaves and begins to dominate, prune it back to a section that previously bore variegated leaves.
• Leaves drop after a change of position: Check whether the plant has been moved into colder air, lower light or a very different watering routine. Give it a warm, bright, stable position and change one care condition at a time.
• White cottony clusters appear where the leaves meet the stems: These are a typical sign of mealybugs. Set the plant apart from your other houseplants, wipe away visible insects and, if needed, choose a treatment labelled for mealybugs on houseplants. Follow the label for any repeat applications. The mealybug guide explains the full process.
• Tiny pale speckles spread across the leaves: Look closely at the undersides for spider mites, especially in warm, dry conditions. Fine webbing is another warning sign. Move the plant away from nearby houseplants while you treat it, clean both sides of the leaves and use a houseplant treatment labelled for spider mites if needed. Repeat treatment only as directed on the label.

Heptapleurum (Schefflera) arboricola ‘Charlotte’ 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.

About the names Schefflera arboricola and Heptapleurum arboricola

Heptapleurum combines Greek hepta, meaning seven, with pleuron, meaning rib or side. The epithet arboricola means tree-dweller.

Joseph Gaertner established the genus Heptapleurum in 1791 in De Fructibus et Seminibus Plantarum, volume 2, page 472.

Bunzō Hayata first described Heptapleurum arboricola in 1916 in Icones Plantarum Formosanarum, volume 6, page 23.

Schefflera arboricola is the familiar former name. Porter P. Lowry II and Gregory M. Plunkett reinstated Heptapleurum for the Asian group formerly included in Schefflera in 2020 in Novon, volume 28. Kew’s World Checklist accepts Heptapleurum arboricola.
