Heptapleurum (Schefflera) arboricola 'Melanie'

Species background and cultivar history

‘Melanie’ is a cream-and-green horticultural selection of Heptapleurum arboricola. The wild species is part of Hainan and Taiwan’s wet forest flora, using woody stems to scramble through vegetation and root where it meets tree trunks.

The species was long called Schefflera arboricola before Heptapleurum was restored in 2020. Both genus names therefore remain connected with ‘Melanie’, while its deeper geographical background belongs to the Hainan-Taiwan forest flora.

Growing a tropical foliage plant indoors

Leaf care: Remove a strong branch that remains entirely green if the cream pattern is to be preserved. Pruning above a node encourages new branches.

Roots and substrate: Let the surface of a loose houseplant mix begin drying before watering thoroughly. Feed lightly as new leaves form, and repot after the roots fill the container.

Light: Give Heptapleurum ‘Melanie’ bright indirect light so its cream-patterned foliage can grow strongly. Pale areas scorch sooner than green ones under sudden direct sun, so introduce mild exposure gradually.

What plant problems can mean

Healthy ‘Melanie’ variegation is firm, repeats on new leaves and remains confined to cream or yellow areas. Stress yellowing spreads more diffusely through leaves of a similar age. When older leaves yellow first, check the soil below the surface. Wet soil, soft roots and continuing leaf loss point to root stress; improve drainage and let more of the mix dry before watering again. Dry, crisp leaves falling from a light pot instead need a thorough soak.

The pale areas also show sun, cold or fertiliser damage before the green tissue. Marks on the exposed side after a move suggest scorch, while brown edges across leaves of several ages call for a check of moisture and residue in the soil. A single branch producing only green leaves is reverting and should be removed at its base. If the whole crown becomes greener and more open, increase the filtered light.

Inspect marked new growth closely for pests. Thrips scar expanding leaflets, spider mites leave pale speckles, scale forms fixed bumps and mealybugs gather as white wax in sheltered joints. Move an infested ‘Melanie’ away from other plants and complete treatment before taking propagation material.

Heptapleurum (Schefflera) arboricola ‘Melanie’ 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.

How did the name change from Schefflera arboricola to 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.
